[U-Boot] [PATCH v3 6/6] arm: Remove unused code in start.S

Simon Glass sjg at chromium.org
Mon Dec 26 19:24:38 CET 2011


Now that we are using the generic relocation framework, we don't need this
code.

Note: Here we lose the ARM1176's enable_mmu code. This seems to duplicate
code already in U-Boot now. Can anyone comment on this?

Changes in v2:
- Make relocation symbols global so we can use them outside start.S

Changes in v3:
- Remove the 'reloc' tag from each commit
- Rebase to master
