def3feb8cb ARM: UniPhier: add empty lowlevel_init to U-boot proper
To remove the ifdef conditional of CONFIG_SKIP_LOWLEVEL_INIT,
add late_lowlevel_init.S to U-Boot proper.

8cddc27965 ARM: UniPhier: move init stack area just below TEXT_BASE
There is no good reason to have the 0x1000 gap between
CONFIG_SYS_INIT_SP_ADDR and CONFIG_SYS_TEXT_BASE.

6a3cffe8e1 ARM: UniPhier: add CONFIG_SPL_MAX_FOOTPRINT
The Boot ROM of UniPhier platform only loads 64KB image.  We should
always make sure that SPL memory footprint is less than that.

ce3a63905b ARM: UniPhier: use CONFIG_SPL_STACK to define SPL stack pointer
Ifdef conditionals for CONFIG options are not Kconfig-friendly.
Instead, define CONFIG_SPL_STACK to prepare for Kconfig moves.

499785b970 ARM: UniPhier: enable Driver Model and UART on SPL
Enable CONFIG_SPL_DM and CONFIG_SPL_SERIAL_SUPPORT, which provide
Driver Model UART support on SPL.

CONFIG_SYS_SPL_MALLOC_{START,SIZE} should be dropped because simple
malloc is preferred on SPL.  Dlmalloc requires some static variables
on .data section that is not available yet for NOR boot mode etc.

53c45d4e1e ARM: UniPhier: switch to xHCI for PH1-Pro4
PH1-Pro4 includes both EHCI and xHCI IP cores.
Unfortunately, U-Boot cannot enable EHCI and xHCI support
simultaneously.  Some users may wish Super-Speed connection.
Disable CONFIG_USB_EHCI_HCD and enable CONFIG_USB_XHCI_HCD.

08fda258ee ARM: UniPhier: revive support card info
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.

35adfc4d25 ARM: UniPhier: move SPL init functions to spl_board_init()

are only necessary for SPL.
Move them to spl_board_init() for clean-up.

75bc8e85b5 ARM: UniPhier: add environment variable to update images in NAND
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

7a3620b246 ARM: UniPhier: detect the number of flash banks at run-time
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.
