The Poplar is broken on eMMC initialization because of commit
2a82a9c95f ("drivers: emmc: dw_mmc: Add response flag into response ID
definition"). It changes the driver behavior on response type handling
in dw_send_cmd(), because MMC_RESPONSE_R(2) and MMC_RESPONSE_R2 are
different things. MMC core is still sending the former while we already
changed to check the latter in dw_mmc driver.
This patch fixes R2 response type in MMC core code. It's the same
thing as what commit 94522ff7f6 ("drivers: mmc: Fix R3 response type
definition") does for R3 response.
With this fix, Poplar is back to work.

At the moment we have two I2C stub drivers (for the Allwinner and the
Marvell platform), which #include the actual .c driver file.
Change this into the more usual design, by renaming and moving the stub
drivers into platform specific header files and including these from the
actual driver file. The platform specific include directories make sure
the driver picks up the right header automatically.

Allwinner 64-bit SoCs all use the Mentor Graphics MI2CV I2C controller
core, with inverted clear quirk.
Add a glue driver for this.
Signed-off-by: Icenowy Zheng <icenowy@aosc.io>
The I2C controller on Allwinner SoCs after A31 has a inverted interrupt
clear flag, which needs to be written 1 (rather than 0 on Marvell SoCs
and old Allwinner SoCs) to clear.
Add such a quirk to mi2cv driver common code.

The Marvell A8K SoCs use the MI2CV IP core from Mentor Graphics, which
is also used by Allwinner.
As Mentor Graphics allows a lot of customization, the MI2CV in the two
SoC families are not compatible, and driver modifications are needed.
Extract the common code to a MI2CV driver.
Signed-off-by: Icenowy Zheng <icenowy@aosc.io>
The I2C controller found in Marvell A8K SoCs (and some older SoCs) mux
status and baudrate registers into the same address, however, it's a
vendor customization, and the original IP core by Mentor Graphics uses
two different addresses for the two registers.
Use anonymous union in the driver, in order to ease code sharing for
other SoC vendors that use this IP core (Allwinner SoCs that are newly
introduced to mainline ATF use this core).

The Mbed TLS drivers, in order to work, need a heap for internal usage.
This heap, instead of being directly referenced by the drivers, now it
is being accessed indirectly through a pointer. Also, the heap, instead
of being part of the drivers, now it is being received through the
plat_get_mbedtls_heap() function. This function requests a heap from the
current BL image which utilises the Mbed TLS drivers.
Those changes create the opportunity for the Mbed TLS heap to be shared
among different images, thus saving memory. A default heap
implementation is provided but it can be overridden by a platform
specific, optimised implemenetation.

This patch does two main things
- It implements the crash console UART init in assembly, as a
hard-coded 115200 8N1 assumed from the 24 MHz clock.
If the clock setup code has not run yet, this code can't work but,
setting up clocks and clock-gates is way out of scope for this type of
recovery function.
- It adds code to write a character out of the NXP UART without using any
stack-based operations when doing so.
- Provides support for crash console in DCE or DTE mode.
Signed-off-by: Bryan O'Donoghue <bryan.odonoghue@linaro.org>
- Adds a simple register read/write abstraction to cut-down on the
amount of typing and text required to access UART registers in this driver.
- Adds a console getc() callback.
- Adds a console putc() callback, translating '\n' to '\r' + '\n'.
- Initializes the MXC UART, take a crude method of calculating the
BAUD rate generator. The UART clock-gates must have been enabled prior
to launching the UART init code.
Special care needs to be taken to ensure the UBIR is initialized before the
UBMR and we need to ensure that UCR2.SRST comes good before trying to
program other registers associated with the UART.
