[ARM] pxa: allow display of uncompress message through STUART (6d3dfe4a) · Commits · e / devices / android_kernel_sony_msm8998

Some boards use UART other than FFUART for the console, E.g. Marvell PXA3xx Form Factor Platform (aka Littleton) uses STUART. This patch modifies the uncompress.h so that display of the uncompress message is routed to the STUART. Signed-off-by:
