Since commit 26b09c022a ("ARM: uniphier: move SBC and Support Card
init code to U-Boot proper"), the System Bus is initialized by
board_init(). The show_board_info() is called from board_init_f()
by default, so the revision register of the Micro Support Card may
not be accessed at this point. Show its revision after the System
Bus is initialized.

We repeated partial moves for CONFIG_SYS_NO_FLASH, but this is
not completed. Finish this work by the tool.
During this move, let's rename it to CONFIG_MTD_NOR_FLASH.
Actually, we have more instances of "#ifndef CONFIG_SYS_NO_FLASH"
than those of "#ifdef CONFIG_SYS_NO_FLASH". Flipping the logic will
make the code more readable. Besides, negative meaning symbols do
not fit in obj-$(CONFIG_...) style Makefiles.
This commit was created as follows:
[1] Edit "default n" to "default y" in the config entry in
common/Kconfig.
[2] Run "tools/moveconfig.py -y -r HEAD SYS_NO_FLASH"
[3] Rename the instances in defconfigs by the following:
find . -path './configs/*_defconfig' | xargs sed -i \
-e '/CONFIG_SYS_NO_FLASH=y/d' \
-e 's/# CONFIG_SYS_NO_FLASH is not set/CONFIG_MTD_NOR_FLASH=y/'
[4] Change the conditionals by the following:
find . -name '*.[ch]' | xargs sed -i \
-e 's/ifndef CONFIG_SYS_NO_FLASH/ifdef CONFIG_MTD_NOR_FLASH/' \
-e 's/ifdef CONFIG_SYS_NO_FLASH/ifndef CONFIG_MTD_NOR_FLASH/' \
-e 's/!defined(CONFIG_SYS_NO_FLASH)/defined(CONFIG_MTD_NOR_FLASH)/' \
-e 's/defined(CONFIG_SYS_NO_FLASH)/!defined(CONFIG_MTD_NOR_FLASH)/'
[5] Modify the following manually
- Rename the rest of instances
- Remove the description from README
- Create the new Kconfig entry in drivers/mtd/Kconfig
- Remove the old Kconfig entry from common/Kconfig
- Remove the garbage comments from include/configs/*.h

Without this patch, the default value of the register is 1, so the mpuclk

For LD20 SoC, the last 64 byte of each DRAM bank is used for the
dynamic training of DRAM PHY. The regions must be reserved in DT to
prevent the kernel from using them. Now gd->bd->bi_dram reflects
the actual memory banks. Just use it instead of getting access to
the board parameters.
Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
U-Boot needs to set up available memory area(s) in dram_init() and
dram_init_banksize(). It is platform-dependent how to detect the
memory banks. Currently, UniPhier adopts the memory banks _alleged_
by DT. This is based on the assumption that users bind a correct DT
in their build process.
Come to think of it, the DRAM controller has already been set up
before U-Boot is entered (because U-Boot runs on DRAM). So, the
DRAM controller setup register seems a more reliable source of any
information about DRAM stuff. The DRAM banks are initialized by
preliminary firmware (SPL, ARM Trusted Firmware BL2, or whatever),
so this means the source of the reliability is shifted from Device
Tree to such early-stage firmware. However, if the DRAM controller
is wrongly configured, the system will crash. If your system is
running, the DRAM setup register is very likely to provide the
correct DRAM mapping.
Decode the SG_MEMCONF register to get the available DRAM banks.
The dram_init() and dram_init_banksize() need similar decoding.
It would be nice if dram_init_banksize() could reuse the outcome
of dram_init(), but global variables are unavailable at this stage
because the .bss section is available only after the relocation.
As a result, SG_MEMCONF must be checked twice, but a new helper
uniphier_memconf_decode() will help to avoid code duplication.

The two arrays ddrphy_{op,ip}_dq_shift_val, occupy more than 3.8 KB
memory footprint, which is significant in SPL.
There are PHY parameters for 5 boards, but they are actually not
board specific, but SoC specific. After all, we just need to have
2 patterns, for LD20 and LD21. Also, the shift values are small
enough to become "short" type instead of "int". This change will
save about 3 KB memory footprint.
