Some UniPhier boards are equipped with an expansion slot that
some optional SRAM/NOR-flash cards can be attached to. So, run-time
detection of the number of flash banks would be more user-friendly.
Until this commit, UniPhier boards have achieved this by (ab)using
board_flash_wp_on() because the boot failed if flash_size got zero.
Fortunately, this problem was solved by commit 70879a9256 (flash:
do not fail even if flash_size is zero).
Now it is possible to throw away such a tricky workaround. This
commit also enables CONFIG_SYS_MAX_FLASH_BANKS_DETECT for further
refactoring.

Introduce a Makefile under arch/$ARCH/ and include it in the
top Makefile (similar to Linux kernel). This allows further
refactoringi like moving architecture-specific code out of global
makefiles, deprecating config variables (CPU, CPUDIR, SOC) or
deprecating arch/$ARCH/config.mk.
In contrary to Linux kernel, U-Boot defines the ARCH variable by
Kconfig, thus the arch Makefile can only included conditionally
after the top config.mk.

Detect the board revision early during boot, and print the decoded
model name.
Eventually, this information can be used for tasks such as:
- Allowing/preventing USB device mode; some models have a USB device on-
board so only host mode makes sense. Others connect the SoC directly
to the USB connector, so device-mode might make sense.
- The on-board USB hub/Ethernet requires different GPIOs to enable it,
although luckily the default appears to be fine so far.
- The compute module contains an on-board eMMC device, so we could store
the environment there. Other models use an SD card and so don't support
saving the environment (unless we store it in a file on the FAT boot
partition...)
Set $fdtfile based on this information. At present, the mainline Linux
kernel doesn't contain a separate DTB for most models, but I hope that
will change soon.

If CONFIG_OF_CONTROL is enabled, lib/fdtdec.c is compiled.
It includes <asm/gpio.h> and then <asm/gpio.h> includes
<asm/arch/gpio.h>. Consequently, all the SoCs that enable
CONFIG_OF_CONTROL must have <asm/arch/gpio.h> even if they do not
support GPIO.
In the first place, GPIO has nothing to do with OF_CONTROL.
It is wrong that lib/fdtdec.c includes GPIO functions; it should
be split into two files, FDT-common things and GPIO things.
It is, however, a pretty big work to fix that correctly.
This is a compromised commit to add a dummy <asm/arch/gpio.h>
to support OF_CONTROL for UniPhier platform. This dummy header
will be removed after FDT-GPIO stuff is fixed correctly.

This adds a fixed mode hdmi driver for the sunxi platform. The fixed
mode is a relatively safe 1024x768, more complete EDID handling is
currently not provided. Only HDMI is supported today.
This code is enabled when HPD detects an attached monitor.
Current config is such that 8MB is shaved off at the top of the RAM.
This avoids several memory handling issues, most significant is the fact
that on linux on ARM you are not allowed to remap known RAM as IO. A
clued in display driver will be able to recycle this reserved RAM in
future though.
cfbconsole was chosen as it provides the most important functionality: a
working u-boot console, allowing for the debugging of certain issues
without the need for a UART.

Ideally, the Linux kernel should get the hardware in its most

subsystems it touches before boot, and usually Linux deals with it, but
on some boards (cm_fx6) the Linux kernel fails to detect the ssd
correctly if sata is used by U-Boot.
Power off sata on OS boot so that Linux will have a clean state to work

Many of references of those macros must be fixed to suppress warnings.

(or add casts to the arguments)
- Use min_t/max_t instead with the appropriate type for the first
