[PATCH/RFC 2/8] serial: core: Add big_endian flag

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




Add a big_endian flag alongside membase, regshift, and iotype.  Most
drivers currently use readl/writel, but if it is necessary to support
a BE SoC, the driver can check this field to see which MMIO accessor
functions to use.
