Overview
---------
BOOTROM starts the cpu at EL3; In this port BL2 will therefore be entered
at this exception level (the Renesas' ATF reference tree [1] resets into
EL1 before entering BL2 - see its bl2.ld.S)
BL2 initializes DDR (and i2c to talk to the PMIC on some platforms)
before determining the boot reason (cold or warm).
During suspend all CPUs are switched off and the DDR is put in
backup mode (some kind of self-refresh mode). This means that BL2 is
always entered in a cold boot scenario.
Once BL2 boots, it determines the boot reason, writes it to shared
memory (BOOT_KIND_BASE) together with the BL31 parameters
(PARAMS_BASE) and jumps to BL31.
To all effects, BL31 is as if it is being entered in reset mode since
it still needs to initialize the rest of the cores; this is the reason
behind using direct shared memory access to BOOT_KIND_BASE and
PARAMS_BASE instead of using registers to get to those locations (see
el3_common_macros.S and bl31_entrypoint.S for the RESET_TO_BL31 use
case).
Depending on the boot reason BL31 initializes the rest of the cores:
in case of suspend, it uses a MBOX memory region to recover the
program counters.

Whereas the GPT table is read with io_block, the binaries to be loaded
(e.g. BL33) cannot use it, as it is not suitable to read them block by
block, or the boot time would be very bad.

commit 97d5db8c5c reverts an update to the
MMC layer that accompanied the original submission of this MMC driver this
is the right-thing-to-do in terms of the MMC spec.
Unfortunately the reversion also breaks this driver. The issue is the i.MX
controller doesn't want MMC_RSP_48 set for MMC_RESPONSE_R2.
The appropriate place to place that constraint is obviously in
drivers/imx/usdhc/imx_usdhc.c not in the shared MMC codebase. This patch
restores the logic the i.MX controller requires without breaking it for
everyone else.

This way it can be reused by other platforms if needed.
Note that this driver is designed to work with the Versatile Express NOR
flash of Juno and FVP. In said platforms, the memory is organized as an
interleaved memory of two chips with a 16 bit word.
Any platform that wishes to reuse it with a different configuration will
need to modify the driver so that it is more generic.

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.

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).
