[U-Boot] [PATCH 1/4] keymile: rework headerfiles for keymile boards

Heiko Schocher hs at denx.de
Mon Apr 12 09:33:14 CEST 2010


- This patch reworks all headerfiles for keymile boards (coge, supx4,
  eter1, suen3).
  Furthermore, a refactoring on the whole environment variables has been
  acomplished.

- Environment variables:
  - grouped into logical blocks (#defines) based on the functionality/purpose
  - short description for most of the variables
  - as much as possible is moved into the common headerfile
  - Keep the kernel command line clean from KM 'specialities'.
    The boardId and hwKey is no longer needed as kernel arguments.
    They are stored in the U-Boot environment and read out from userspace
    later with the help of fw_printenv or equivalent tools.
- km8xx: default environment partitioning corrected
- Check the board id and the HW key stored in the environment with the values
  stored in IVM. Board id and hardware key are patched into the environment
  when building a keymile bootpackage.
- introduces the variable "initial_boot_bank" to the default
  environment. The "actual_bank" is set to this value on first
  startup.
  It is normally set to 0. So the behaviour is as before.
  If set to != 0, the first actual_bank is set to this
  value as well. Thus a bootpackage can define a boot
  bank other than 0.
