This patch series updates all MIPS asm header files containing I/O code as well as processor, register and assembly definitions. The source of the update are the MIPS asm header files of linux-4.4.
The main goal is to get a complete set of I/O accessors on MIPS and to support platform-specific address spaces and mappings. Also a working ioremap() implementation will be added, which supports platform-specific callbacks. Furthermore support for bit manipulating I/O accessors (clrbits_X, setbits_X, clrsetbits_X) will be added.
The patch series is also available on git://git.denx.de/u-boot-mips.git in branch mips_io_v1 and based on next branch.
@Wills I changed map_physmem() and used the new and working ioremap() function. Thus you can discard your patch.
@Wills, Purna You can use now ioremap() directly in your drivers. You can also use the new bit manipulating I/O accessors as requested by Marek. Please rebase and test your patch series against this series, thanks.
Thanks Daniel. Rebased my PIC32 patches on 'mips_io_v1' branch and tested functionality to work fine. Also updated drivers to use ioremap() (instead of pic32_ioremap()) and clrsetbits_le() wherever applicable.
