      marvell: uart: a3720: Fix macro name for 6th bit of Status Register · b8e637f4
      Pali Rohár authored 
      

This patch does not change code, it only updates comments and macro name
for 6th bit of Status Register. So TF-A binary stay same.

6th bit of the Status Register is named TX EMPTY and is set to 1 when both
Transmitter Holding Register (THR) or Transmitter Shift Register (TSR) are
empty. It is when all characters were already transmitted.

There is also TX FIFO EMPTY bit in the Status Register which is set to 1
only when THR is empty.

In both console_a3700_core_init() and console_a3700_core_flush() functions
we should wait until both THR and TSR are empty therefore we should check
6th bit of the Status Register.

So current code is correct, just had misleading macro names and comments.
This change fixes this "documentation" issue, fixes macro name for 6th bit
of the Status Register and also updates comments.

      marvell: uart: a3720: Implement console_a3700_core_getc · 74867756
      Pali Rohár authored 
      

Implementation is simple, just check if there is a pending character in
RX FIFO via RXRDY bit of Status Register and if yes, read it from
UART_RX_REG register.

Implementation is simple, just wait for the TX FIFO to be empty.

Without this patch TF-A on A3720 truncate the last line:

  NOTICE:  BL31: Built : 16:1

With this patch TF-A on A3720 print correctly also the last line:

      Don't return error information from console_flush · 831b0e98
      Jimmy Brisson authored 
      

And from crash_console_flush.

We ignore the error information return by console_flush in _every_
place where we call it, and casting the return type to void does not
work around the MISRA violation that this causes. Instead, we collect
the error information from the driver (to avoid changing that API), and
don't return it to the caller.

      plat: marvell: ap807: implement workaround for errata-id 3033912 · 5e4c97d0
      Stefan Chulski authored 
      

ERRATA ID: RES-3033912 - Internal Address Space Init state causes
a hang upon accesses to [0xf070_0000, 0xf07f_ffff]
Workaround: Boot Firmware (ATF) should configure CCU_RGF_WIN(4) to
split [0x6e_0000, 0xff_ffff] to values [0x6e_0000, 0x6f_ffff] and
[0x80_0000, 0xff_ffff] that cause accesses to the segment of
[0xf070_0000, 0xf07f_ffff] to act as RAZWI. Reuse common
work-around code for both AP806 and AP807.

      plat: marvell: armada: add support for loading MG CM3 images · 81646055
      Grzegorz Jaszczyk authored 
      

In order to access MG SRAM, the amb bridge needs to be configured which is
done in bl2 platform init.

For MG CM3, the image is only loaded to its SRAM and the CM3 itself is
left in reset. It is because the next stage bootloader (e.g. u-boot)
will trigger action which will take it out of reset when needed. This
can happen e.g. when appropriate device-tree setup (which has enabled
802.3 auto-neg) will be chosen. In other cases the MG CM3 should not be
running.

      drivers: marvell: comphy-a3700: support SGMII COMPHY power off · 629dd61f
      Marek Behún authored 
      

Add support for powering off the SGMII COMPHY (on lanes 0 and 1).
This is needed sometimes on Turris Mox when using KEXEC.

There is also another benefit of a little energy saving when the given
network interface is down.

      drivers: marvell: comphy-a3700: fix USB3 powering on when on lane 2 · b662232d
      Marek Behún authored 
      

When USB3 is on lane 2 and indirect register access is used, the polling
at the end of the mvebu_a3700_comphy_usb3_power_on function is
incorrect.

The LOOPBACK_REG0 register should not be used at all. Instead we have to
write the LANE_STATUS1 register address (with offset
USB3PHY_LANE2_REG_BASE_OFFSET) into the indirect address register and
then we should poll indirect data register.

This fixes problems on Turris Mox, which uses lane 2 for USB3.

      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.
