Subject[PATCH 6/7] ARM: iop32x: make mach/uncompress.h independent of mach/hardware.h
Date
All supported uarts use the same address: IQ80321_UART and IQ31244_UART
are both defined to the default value of 0xfe800000. By using that as
the address unconditionally, all dependencies on other machine headers
can be avoided.
