However, as AR9331 allows to remap boot ROM to 0xbf000000 it's better to assume that boot ROM starts at 0xbf000000.

	8891fcc Browse files » MIPS: pbl: add pbl_blt macro ... Barebox' PBL is able to initialize SoC's memory controller, but it can be used only if PBL runs from ROM or on-chip SRAM. MIPS architecture standard boot vector is 0xbfc00000 so on most MIPS SoCs all addresses higher than 0xbfc00000 belong to boot ROM or on-chip SRAM. Thus there's a simple criterion to check if PBL runs from ROM: just check if current PC is higher than 0xbfc00000. Some MIPS boards have ROM start address lower than 0xbfc00000 so it's reasonable to make ROM start address checking board-dependant. The pbl_blt macro checks if current pc is lower than the first argument (ROM start address). If so then next instruction executed is defined by the second argument of the macro.

	b792124 Browse files » rework remap_range ... remap_range is for remapping regions with different cache attributes. It is implemented for ARM and PowerPC only, the other architectures only provide stubs. Currently the new cache attributes are passed in an architecture specific way and the attributes have to be retrieved by calls to mmu_get_pte_cached_flags() and mmu_get_pte_uncached_flags(). Make this simpler by providing architecture independent flags which can be directly passed to remap_range() Also provide a MAP_ARCH_DEFAULT flag and a arch_can_remap() function. The MAP_ARCH_DEFAULT defaults to whatever caching type the architecture has as default. the arch_can_remap() function returns true if the architecture can change the cache attributes, false otherwise. This allows the memtest code to better find out what it has to do. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Sascha Hauer committed on 3 Nov 2015
