OMAP2 not booting in 2.6.27-rc9?

Hi

At least N810 hangs somewhere executing local_flush_tlb_all() in omap_map_sram. Last printk is before that call.

Merge current mainline tree into linux-omap tree

Merge branches 'master' and 'linus'

Broken on 2430SDP too. Will look further.

Hi Jarkko,

does the following patch fix the problem for you?

Commit 1c957036bbd912322793da676d05e169abf24782 breaks booting on OMAP2; the SRAM is mapped on top of the L4 interconnect. This causes the system to hang early in boot in omap_map_sram() during a TLB flush. Fix by moving SRAM elsewhere in the memory map.

Reported by Jarkko Nikula <[email protected]>. This patch is a collaboration with Tony Lindgren <[email protected]> and Kevin Hilman <[email protected]>.

Tested on 2430SDP.
