This commit renames the function pointer of type progress_cb_t for file_upload(). That might help to avoid potential confusion with other routines that use a boolean "progress" parameter to indicate whether progress information is desired (at all). Signed-off-by: -

Until now, the function would always pass `true` as the "progress" parameter to aw_write_buffer(). This has the potential drawback of limiting the maximum USB transfer size. By selectively passing `false` instead (with no progress function active), we hint that aw_write_buffer() and subsequent routines don't have to care about callbacks; so that usb_bulk_send() is free to select a transfer size of AW_USB_MAX_BULK_SEND.

This way we don't have to introduce new options for retrieving version info. For those programs that do not output their usage by default (e.g. because they would process stdin), you may pass a "-?" option to get help - and thus version information. Signed-off-by: -

* fel: Add the ability to pass uEnv-style data via FEL The corresponding format is recognized by having the environment data (= text) start with a special "#=uEnv" marker. Upon transfer of such a file, sunxi-fel will detect this condition, and set a field in the SPL header accordingly - which in turn also requests U-Boot to auto-import it (i.e. merge with the default environment). (Note that this requires a U-Boot version that knows about the new meaning of this field, namely v2016.09 or later. Older U-Boot versions will fail to import the uEnv-style data.) Signed-off-by:

This commit adds a new "reset64 <addr>" command "rmr32" that could be helpful with new 64-bit SoCs. It takes an entry point (address) parameter, stores it via RVBAR and then issues a RMR write to request a warm boot into AArch64 mode. For now, this is useful with the boot process of A64, where we might wish to transfer control to a 64-bit binary (for ATF or U-Boot). See e.g. http://linux-sunxi.org/Pine64#Boot_sequence Signed-off-by:

The SCTLR bits are somewhat different because the V bit is set to 0 on A64 (Low exception vectors, base address 0x00000000) and the UNK bit (Reads of this bit return an UNKNOWN value) is also not the same as on the other SoCs. So the SCTLR check can be relaxed. Changes in v2: - Because the SRAM A and SRAM C reside back-to-back in the address space, it is possible to use 40 KiB of SRAM by the SPL for its code+data+stack. So the FEL backup storage is moved from 0x18000 to 0x1A000 to support this. Signed-off-by:Siarhei Siamashka <siarhei.siamashka@gmail.com>

This allows the SRAM section A2 to be exclusively used by the OpenRISC core. There are no substantial differences between H3 and A10/A13/A20. It just has 64 KiB of SRAM starting at the address 0x0 instead of 48 KiB. Signed-off-by: -

This allows the SRAM section A2 to be exclusively used by the OpenRISC core. Regarding the potential U-Boot SPL size. The SRAM section A1 only has 32 KiB. But at least the stack can be set at the end of the SRAM section B. Or runtime UCL or LZO decompression can be used to unpack the SPL code to 0x24000-0x2FFFF and have 48 KiB of available space there.

Previously the backup area was allocated at the address 0x8000. This is not very good because it means that the U-Boot SPL can only safely use memory at addresses 0x0000-0x7FFF (32 KiB). But if we move the backup area to the end of the SRAM A4, this can allow U-Boot SPL to use memory 0x0000-0x9FFF (40 KiB). The BROM can't load such large SPLs from the SD card. But the SPL still can move its stack up to the 40 KiB boundary or do UCL or LZO decompression at runtime to squeeze more code into it. This patch makes the sunxi-fel tool compatible with 40 KiB SPLs, even though the current U-Boot releases do not use them yet. Signed-off-by:

This patch makes use of the new aw_fel_readl_n() function to output the first four 32-bit values (SID key) from an SoC-specific address. The corresponding e-fuses may not necessarily start at the SID "base" address, e.g. on H3/A83T they are at <base+0x200>. Note: SoC support is currently incomplete. In particular, reading the SID on A31(s) is unsupported. Accessing it there is complicated by the fact that Allwinner moved this information from the SoC into the PMIC/AXP221. Signed-off-by: -

Doing certain operations may need uploading and executing code on the device. For example, such operations right now are reading/writing ARM CP15 coprocessor registers. Uploading the code to the device is naturally overwriting some part of SRAM as a side effect. Right now it is not a problem, because the CP15 coprocessor registers are only accessed as part of uploading and executing U-Boot SPL. They are nicely timed not to cause problems and the temporary scratch area gets overwritten by the SPL code anyway. But if we decide to provide access to such operations via command line interface, then any side effects may potentially cause problems for the users. Consider the following scenario: sunxi-fel clear 0x2000 0x100 \ advanced-command-which-uploads-and-executes-code \ hexdump 0x2000 0x100 The user may rightfully expect that clearing a buffer in SRAM to zero and then reading it back should show all zero bytes. But inserting advanced commands in the middle may cause data corruption. In order to resolve this problem, just move the scratch area away from the 0x2000-0x5BFF addresses range. These particular addresses are already known to the users as a safe place for their bare metal expariments in FEL mode. The "sunxi-fel spl" command is a special case though and it is expected to overwrite data in this area too. A possible alternative would be to just backup & restore data in the scratch area. But this has some disadvantages: 1. Extra code in the sunxi-fel tool and extra roundtrips over USB to do the backup/restore job. 2. If we allow the OpenRISC core to use the 0x2000-0x5C00 range in SRAM A1, then this becomes unsafe and racy (we can't really backup & restore data without causing a temporarily glitch for the currently running code on the OpenRISC core). To sum it up. With this patch we make it so that now the 0x2000-0x5BFF range is freely available for the users of the sunxi-fel tool. The 0x1000-0x1FFF range is off limits (the upper part of it is used by the FEL IRQ handler, the lower part of it is reserved for internal use by the sunxi-fel tool). The 0x0000-0x0FFF addresses range is reserved for passing data from the SPL to the main U-Boot binary (via the SPL header) and is also off limits. Signed-off-by:

For Linux, this requires additional #defines, see https://gist.github.com/panzi/6856583#gistcomment-1656524 Placing those #defines into portable_endian.h would mean we depend on the specific order of #includes (whatever pulls in endian.h first, including other system includes). Avoid this by using symbols provided "globally" via the Makefile. Also nuke the _NETBSD_SOURCE definition in fel.c Signed-off-by:

Our previous include file only supplied a very limited set of wrapper redefinitions for platforms that define __APPLE__ (i.e. Mac OS). In particular, some needed big endian conversions were missing, causing "symbol(s) not found" errors when linking. Instead of patching the existing file, let's do away with it completely and replace it by something more sophisticated. The portable_endian.h used is in the public domain, and was taken from https://gist.github.com/panzi/6856583 Signed-off-by:

Commit 472ac475 introduced a possible regression by relying on the availability of libusb_strerror(). There are libusb versions out there _not_ offering this function, which breaks compilation. Introducing a separate helper function allows us to work around this, refactor existing code and have more streamlined error reporting - avoiding the message string retrieval where needed. The usb_error() function can also optionally abort execution with a given exit code. Signed-off-by:

Commit d99d59c0 introduces a bug when the "spl" command is used with a file that contains a U-Boot binary. "spl" will now try to execute it, while it's not supposed to. (The command should only start the SPL.) This patch brings back the `uboot_autostart` flag, which is meant to remain `false` for the "spl" command, and gets set by "uboot" only. Signed-off-by:

This patch adds an "echo-gauge" command that is intended for use with sunxi-fel's output piped into the dialog utility. "echo-gauge" will output its string argument in a way that updates (i.e. overwrites) the prompt text that dialog displays, so it's possible to change that inbetween file transfers from sunxi-fel. Example: sunxi-fel uboot ${UBOOT} \ echo-gauge "Uploading kernel (1/2)" \ write-with-gauge 0x42000000 ${KERNEL} \ write 0x43100000 ${SCRIPT} \ echo-gauge "Uploading rootfs (2/2)" \ write-with-gauge 0x44000000 ${ROOTFS} \ | dialog --gauge "" 6 70 Signed-off-by: -

This patch adds some additional commands, and implements corresponding progress callbacks that produce output for the 'dialog' utility: http://invisible-island.net/dialog/dialog.html The simple "*-with-gauge" just emits percentage numbers, line by line, while "*-with-xgauge" outputs extended information to update the dialog prompt. Both are meant for directly piping the output: sunxi-fel write-with-gauge <...> | dialog --gauge "FEL upload" 6 70 Signed-off-by:

This patch moves some code out of the "write" handler, with the intention to reuse it later for similar commands. At the same time, it also discards the previous transfer rate output when using "-v", as that has become redundant with the 'progress bar' display available by "-p". Signed-off-by:

This patch adds a boolean parameter "progress" to several functions. When set (true), it will cause usb_bulk_send() to notify the progress framework, using progress_update() to convey the current transfer status. The feature gets enabled for the "write" command, and is forced inactive in most other places, e.g. aw_fel_write_uboot_image(). Also, we specifically want the internal use of aw_fel_write() to never use it. Signed-off-by:
