Subject: [PATCH] cpm_uart: use DPRAM for early console
X-Git-Tag: v2.6.13-rc4~25^2~18
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4e4b7952cd34af4dd78e012265d4bc858db6adf3;p=pandora-kernel.git

[PATCH] cpm_uart: use DPRAM for early console

m8xx_cpm_hostalloc() can't rely on using the coherent DMA allocator early
on boot because the VM is not fully up yet.  Change it to use the on-board
DPRAM instead.

The current code relies on the "bootmem_page" allocated by
m8xx_cpm_reset(), which must be killed.

This is done in v2.4 but has never been forward ported to v2.6.
