      Remove several warnings reported with W=1 · 609e053c
      Ambroise Vincent authored 
      

Improved support for W=1 compilation flag by solving missing-prototypes
and old-style-definition warnings.

The libraries are compiling with warnings (which turn into errors with
the Werror flag).

Outside of libraries, some warnings cannot be fixed without heavy
structural changes.

      drivers: Remove TODO from io_storage · 9a2fffb8
      Paul Beesley authored 
      

This TODO was added five years ago so I assume that there is not
going to be a shutdown API added after all.

      drivers: synopsys: Fix synopsys MMC driver · 3d0f30bb
      Tien Hock, Loh authored 
      

There are some issues with synopsys MMC driver:
- CMD8 should not expect data (for SD)
- ACMD51 should expect data (Send SCR for SD)
- dw_prepare should not dictate size to be MMC_BLOCK_SIZE, block size is
now handled in the dw_prepare function
- after the CMD completes, when doing dw_read, we need to invalidate cache
and wait for the data transfer to complete
- Need to set FIFO threshold, otherwise DMA might never get the interrupt
to read or write

      drivers: mmc: Fix some issues with MMC stack · a468e756
      Tien Hock, Loh authored 
      

Some bugs in MMC stack needs to be fixed:
- scr cannot be local as this will cause cache issue when invalidating
after the read DMA transfer is completed
- ACMD41 needs to send voltage information in initialization, otherwise the
command is a query, thus will not initialize the controller
- when checking device state, retry until the retries counter goes to zero
before failing

      rpi3: sdhost: SDHost driver improvement · 2c8ef2ae
      Ying-Chun Liu (PaulLiu) authored 
      

This commit improves the SDHost driver for RPi3 as following:
 * Unblock MMC_CMD(17). Using MMC_CMD(17) is more efficient on
   block reading.
 * In some low probability that SEND_OP_COND might results CRC7
   error. We can consider that the command runs correctly. We don't
   need to retry this command so removing the code for retry.
 * Using MMC_BUS_WIDTH_1 as MMC default value to improve the stability.
 * Increase the clock to 50Mhz in data mode to speed up the io.
 * Change the pull resistors configuration to gain more stability.

      ti: k3: common: Add support for runtime detection of GICR base address · b5443284
      Andrew F. Davis authored 
      

Valid addresses for GICR base are always a set calculable distance from
the GICD and is based on the number of cores a given instance of GICv3 IP
can support. The formula for the number of address bits is given by the
ARM GIC-500 TRM section 3.2 as 2^(18+log2(cores)) with the MSB set to
one for GICR instances. Holes in the GIC address space are also
guaranteed to safely return 0 on reads. This allows us to support runtime
detection of the GICR base address by starting from GIC base address plus
BIT(18) and walking until the GICR ID register (IIDR) is detected. We
stop searching after BIT(20) to prevent searching out into space if
something goes wrong. This can be extended out if we ever have a device
with 16 or more cores.

      Sanitise includes across codebase · 09d40e0e
      Antonio Nino Diaz authored 
      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.

      GIC: Remove lowest priority constants · 35cd9e81
      Jeenu Viswambharan authored 
      

The GIC lowest priority values for each world depends on the number of
priority values implemented in hardware. These constants currently
defined in gic_common.h only meant to enumerate lowest possible
architectural values. Since these values are not used in generic code or
upstream platforms, and that general use of these constants can be
wrong, remove these. Platforms should either define and use these as
appropriate, or determine correct values at run time.
