In UniPhier SoCs before ProXstream2 and PH1-LD6b, two address spaces
0x00000000 - 0x0fffffff
0x40000000 - 0x4fffffff
are both mapped to the external bus (also called system bus),
so either was OK.
In the newest two SoCs, the former (0x00000000 - 0x0fffffff) is
assigned for the serial NOR interface.
Going forward, use the latter for the external bus.

Historically (for compatibility with very old platforms), two
different types of micro support cards have been used with the
UniPhier SoC development boards. It has been painful to maintain
both. Having one of them is enough.

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.
