[U-Boot] [PATCH 13/22] omap4: separate mux settings into essential and non essential parts

Aneesh V
2011-02-28T11:46:22Z

Do the essential part from SPL and non-essential part from U-Boot
- Essential part is what is essential for u-boot to function
- Essential part is also largely board independent(at least
as of now)
- So essential part is moved out to SoC directory instead of
keeping in board directory. This helps in having single SPL
that works for Panda and SDP.
- Non-essential part is what is set by u-boot for kernel to
function correctly
- Ideally non-essential part should be phased out eventually
