Since now the generic console_t structure holds the UART base address as well, let's use that generic location and drop the UART driver specific data structure at all. Change-Id: I058f793e4024fa7291e432f5be374a77faf16f36 Signed-off-by: Andre Przywara <andre.przywara@arm.com>

The implementation of the heap function plat_get_mbedtls_heap() becomes mandatory for platforms supporting TRUSTED_BOARD_BOOT. The shared Mbed TLS heap default weak function implementation is converted to a helper function get_mbedtls_heap_helper() which can be used by the platforms for their own function implementation.

Recently upstreamed changes to OP-TEE mean that it is possible for OP-TEE to provide a DTB overlay directly to subsequent boot stages thus negating the requirement to bundle a DTB in the FIP. This patch switches off the dependency on the DTB in the FIP descriptor instead we will provide the necessary data as an overlay from OP-TEE.

Enforce full include path for includes. Deprecate old paths. The following folders inside include/lib have been left unchanged: - include/lib/cpus/${ARCH} - include/lib/el3_runtime/${ARCH} The reason for this change is that having a global namespace for includes isn't a good idea. It defeats one of the advantages of having folders and it introduces problems that are sometimes subtle (because you may not know the header you are actually including if there are two of them). For example, this patch had to be created because two headers were called the same way: e0ea0928 ("Fix gpio includes of mt8173 platform to avoid collision."). More recently, this patch has had similar problems: 46f9b2c3 ("drivers: add tzc380 support"). This problem was introduced in commit 4ecca339 ("Move include and source files to logical locations"). At that time, there weren't too many headers so it wasn't a real issue. However, time has shown that this creates problems. Platforms that want to preserve the way they include headers may add the removed paths to PLAT_INCLUDES, but this is discouraged.

All identifiers, regardless of use, that start with two underscores are reserved. This means they can't be used in header guards. The style that this project is now to use the full name of the file in capital letters followed by 'H'. For example, for a file called "uart_example.h", the header guard is UART_EXAMPLE_H. The exceptions are files that are imported from other projects: - CryptoCell driver - dt-bindings folders - zlib headers Change-Id: I50561bf6c88b491ec440d0c8385c74650f3c106e Signed-off-by: Antonio Nino Diaz <antonio.ninodiaz@arm.com>

Even though at this point plat_crash_console_flush is optional, it will stop being optional in a following patch. The console driver of warp7 doesn't support flush, so the implementation is a placeholder. TI had ``plat_crash_console_init`` and ``plat_crash_console_putc``, but they weren't global so they weren't actually used. Also, they were calling the wrong functions. imx8_helpers.S only has placeholders for all of the functions.

Previous changes in this series made the necessary driver additions and updates. With those changes in-place we can add the platform.mk and bl2_el3_setup.c to drive the boot process. After this commit its possible to build a fully-functional TF-A for the WaRP7 and boot from the BootROM to the Linux command prompt in secure or non-secure mode.

This patch adds a callback into the BootROM's provided High Assurance Boot (HAB) failsafe function when panicking i.e. the call is done without making use of stack. The HAB failsafe function allows a piece of software to call into the BootROM and place the processor into failsafe mode. Failsafe mode is a special mode which presents a serial download protocol interface over UART or USB at the time of writing. If the board has been set into secure mode, then only a signed binary can be used to recover the board. Thus failsafe gives a putatively secure method of performing a secure recovery over UART or USB.

In order to enable compile time differences in HAB interaction, we should split out the definition of the base address of the HAB API. Some version of the i.MX series have different offsets from the BootROM base for the HAB callback table. This patch defines the header into which we will define the i.MX7 specific offset. The offset of the i.MX7 function-callback table is simultaneously defined. Once done, we can latch a set of common function pointer locations from the offset given here and if necessary change the offset for different processors without any other code-change. For now all we support is i.MX7 so the only offset being defined is that for the i.MX7. Signed-off-by: Bryan O'Donoghue <bryan.odonoghue@linaro.org> Reviewed-by: Ryan Harkin <ryan.harkin@linaro.org>

In order to have some common code shared between similar SOCs its pretty common to have IP blocks reused. In reusing those blocks we frequently need to map compatible blocks to different addresses depending on the SOC. This patch adds a basic memory map of the i.MX7 based on the "Cortex-A7 Memory Map" section 2.12 of "i.MX7Solo Applications Processor Reference Manual, Rev 0.1 08/2016" In memory map terms the i.MX7S and i.MX7D are identical with the D variant containing two Cortex-A7 cores plus a Cortex-M core and the S variant containing one Cortex-A7 and one Cortex-M.
