Add support the "mmio32" earlycon option for the pl011 device. If specified in the earlycon parameter, all reads/writes to pl011 registers during early console will use 32-bit accessors. Normally the function uses 8-bit writes. Normal console uses the "access_32b" field of the vendor data structure to determine whether the registers needs 32-bit accessors. Early console is used before the vendor data is available, so we need a different mechanism to choose the accessor. Example: earlycon=pl011,mmio32,0x3ced1000 Signed-off-by: Timur Tabi <redacted> --- This patch applies on top of Russell's 12-part amba-pl011.c patchset.
Which I didn't apply, so can you resend this after he resends his? thanks, greg k-h
