Subject: [PATCH 3/3] st7735fb: Make FB native endian on little endian platforms
|
||||
|
||||
This is a quick unoptimized implementation of a shadow swap buffer
|
||||
which is engaged on little endian platforms. It's not DMA safe
|
||||
at this point nor is it particularly optimized during updates.
|
||||
This is ok atm since the point is to be compatible with all the
|
||||
user space code out there that assumes that all FBdevs are native
|
||||
endian.
|
||||
|
||||
Now things like "cat foo.rgb565 > /dev/fb0" work as well as standard
|
||||
apps like fbv with no byte swapping mods.
