of/fdt: make memblock maximum physical address arch configurable

2015-08-24T09:23:13+00:00

When parsing the memory nodes to populate the memblock memory table, we check against high and low limits and clip any memory that exceeds either one of them. However, for arm64, the high limit of (phys_addr_t)~0 is not very meaningful, since phys_addr_t is 64 bits (i.e., no limit) but there may be other constraints that limit the memory ranges that we can support. So rename MAX_PHYS_ADDR to MAX_MEMBLOCK_ADDR (for clarity) and only define it if the arch does not supply a definition of its own.

dt/fdt: add empty versions of early_init_dt_*_memory_arch

2015-06-19T01:35:46+00:00

With the addition of commit 0166dc1 (of: make CONFIG_OF user selectable), architectures which don't enable memblock and don't have their own early_init_dt_*_memory_arch implementations will break when CONFIG_OF is enabled. Really, we should have better separation of CONFIG_OF and CONFIG_OF_EARLY_FLATTREE, but doing that will require quite a bit of shuffling of architecture code. That will have to wait for another day.

of/fdt: split off FDT self reservation from memreserve processing

2015-06-02T15:31:25+00:00

This splits off the reservation of the memory occupied by the FDT binary itself from the processing of the memory reservations it contains. This is necessary because the physical address of the FDT, which is needed to perform the reservation, may not be known to the FDT driver core, i.e., it may be mapped outside the linear direct mapping, in which case __pa() returns a bogus value.

of/fdt: Make fdt blob input parameters of unflatten functions const

2015-05-28T18:00:25+00:00

Operations to unflatten fdt blobs never modify the input blobs, hence make them const. Now we no longer need to cast arbitrary const data to "void *" when calling of_fdt_unflatten_tree(). Signed-off-by: Geert Uytterhoeven Signed-off-by: Rob Herring

of/fdt: Remove "reg" data prints from early_init_dt_scan_memory

2015-04-15T00:35:43+00:00

Commit 51975db0b7333 ("of/flattree: merge early_init_dt_scan_memory() common code") consolidated some code from PowerPC (typically big-endian), and ended-up adding a pr_debug() printing reg properties in big-endian (DT native) format, not CPU endian. This debug print suffers from two problems: - we only print 4 "reg" values, while there could be more on typical systems having multiple memory ranges - we print these 4 "reg" values in FDT endianess, that is big-endian, and these values could be confusing for little-endian configurations Since we are already printing the base address and size of the memory regions parsed by early_init_dt_scan_memory() later in a way that is both endian correct, and takes into account arbitrary number of memory banks, just remove that part of the debug print.
