[U-Boot] [PATCH v2 0/5] x86: Move x86 to use board_init_f_mem() instead of assembler

[Simon Glass]

Much of the early-init assembler on x86 can be removed if we use the new
board_init_f_mem() function. At present only PowerPC uses it, but we should
try to move more archs over.

This has been contemplated for a while but it is time to take the plunge.

Changes in v2:
- Correct logic to round down instead of up
- Drop unused 'reserve_size' argument
- Rename arch_setup_gdt() to arch_setup_gd()
- Expand the comment about the 64-byte stack space
- Fix a comma which should be a period
- Add a comment as to why we can't compile the weak arch_setup_gd() on x86
- Don't rely on value of %edx from board_init_f_mem()

Simon Glass (5):
  x86: Remove init_gd() function
  Align global_data to a 16-byte boundary
  Allow arch-specific setting of global_data in board_init_f_mem()
  x86: Move the GDT into global_data
  x86: Switch to using generic global_data setup
