[Qemu-devel] [PATCH] Add Palm Tungsten|C support

["Marek Vašut" <marek.vasut@gmail.com>]

[-- Attachment #1: Type: text/plain, Size: 351 bytes --]

Hi,

this patch adds Palm TC support. It's a PXA based handheld device (unlike
PalmTE defined in palm.c which is OMAP) so I decided to separate these and
create new palmpxa.c . Near future plan is to add basic support for other
pxa-based palm models as well. Please consider applying.

Signed-off-by: Marek Vasut <marek.vasut@gmail.com>

Thanks
Marek
