Remove this board as this is the only one last user of eeprom_probe(),
which is pretty non-standard stuff.
This patch also removes all the PHP, SQL and CSS stuff from U-Boot,
which probably makes U-Boot a bit less IoT ;-)

The file board/Marvell/include/mv_gen_reg.h is incompatible with
the GPL (see for example the "MARVELL RESERVES THE RIGHT AT ITS SOLE
DISCRETION TO REQUEST THAT THIS CODE BE IMMEDIATELY RETURNED TO
MARVELL" clause). As this cannot be fixed, we remove the file and all
code that depends on it. Fortunately this only affects some very old
boards that have long reached EOL:
CPCI750
DB64360
DB64460
p3m750
p3m7448

Switch to the common spl.h file and zap the arch/spl.h . Since the arch/spl.h
contained various ad-hoc symbols, zap those symbols as well and rework the
board configuration a little so it doesn't depend on them.

Move this initialization code to proper place. The misc_init_r()
function is called way too late and the platform initialization
code should be executed much earlier.

Because CONFIG_MMU is never defined in U-Boot,
the non-MMU code in debug.S is always used.
Unfortunately, the number of arguments of the addruart macro
in Linux is different between MMU and non-MMU.
This causes a build error when importing some debug macros
using the third argument. (For ex. arch/arm/include/debug/exynos.S)
Pass the third argument to the non-MMU addruart to avoid such a problem.

We have not had a good method to debug the early boot stage such as
lowlevel_init function. I guess developers generally use dedicated
debuggers for that, but it is difficult in some cases.
(For example, my debugger cannot connect to the ARM processor when
it is in the secure state. It sometimes happens when I need to
debug the early boot stage on ARM SoCs with secure extension.)
The low level debug feature in Linux would be also helpful for U-boot
when we are stucking in nasty problems where the console is not
available yet.
You have to enable CONFIG_DEBUG_LL to use this feature.
For now, only 8250-compatible UART devices are supported.
You can add a header file under arch/arm/include/debug/ directory
to support your UART device if necessary.

Add a Kconfig option which users can select when they want to boot older
kernels, e.g. the linux-sunxi 3.4 kernels. For now this just forces the pll5
"p" value to 1 (divide by 2) as that is what those kernels are hardcoded too,
in the future this may enable further workarounds.

The A23 only has UART0 muxed with MMC0. Some of the boards we
encountered expose R_UART as a set of pads.
Add support for R_UART so we can have a console while using mmc.

The A31, A23 and later SoCs have an extra pin controller, called CPUs_PIO
or R_PIO, which handles pin banks L and beyond.
Also add a clear description about SUNXI_GPIO_BANKS, stating it only
counts the number of pin banks in the _main_ pin controller.

The basic blocks of the A23 are similar to the A31 (sun6i). Re-use
sun6i code for initial clock, gpio, and uart setup.
There is no SPL support for A23, as we do not have any documentation

None of the known sunxi devices actually use mmc1 routed through PH, where
as some devices do actually use mmc1 routed through PG, so change the routing
of mmc1 to PG. If in the future we encounter devices with mmc1 routed through
PH, we will need to change things to be a bit more flexible.

sunxi SOCs can boot from both mmc0 and mmc2, detect from which one we're
booting, and make that one "mmc dev 0" so that a single u-boot binary can
be used for both the onboard eMMC and for external sdcards.
When we're booting from mmc2, we make it dev 0 because that is where the SPL
will load the tertiary payload (the actual u-boot binary in our case) from,
see: common/spl/spl_mmc.c, which has dev 0 hardcoded everywhere.
