Device Tree really improves code maintainability and is now
available for SPL too.
This is the state-of-the-art implementation in U-boot.
The board files (platform data) are no longer needed.

Currently, the environment variables "norboot" and "nandboot" only

This commit adds environments useful for booting Linux with separate

Since commit 92ac520821 (net: Remove all references to
CONFIG_ETHADDR and friends), the ethernet device on UniPhier boards
is not working because of the incorrect (all-zero) MAC address.
Enable CONFIG_NET_RANDOM_ETHADDR to generate the random one.

We really don't want boards defining fixed MAC addresses in their config
so we just remove the option to set it in a fixed way. If you must have
a MAC address that was not provisioned, then use the random MAC address
functionality.

Since commit 0365ffcc0b (generic-board: show model name in
board_init_f() too), the support card information has not been
displayed because check_support_card() is invoked only when
show_board_info() fails to get the model name from Device Tree.
This commit adds misc_init_f() function to call check_support_card()
from there.

To boot UniPhier boards with the NAND boot mode, two images
(u-boot-spl.bin and u-boot-dtb.img) must be written at the correct
offset addresses.
TFTP downloading is useful to update such images in the NAND device.
We generally do:
=> nand erase 0 0x100000
=> tftpboot u-boot-spl.bin
=> nand write $loadaddr 0 0x10000
=> tftpboot u-boot-dtb.img
=> nand write $loadaddr 0x10000 0xf0000
It is a tedious and error-prone operation.
This commit provides the shorthand:
=> run nandupdate

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.
