This patch extends the capability of libfdt to parse the contents of device trees in a similar manner to fdt_address_cells and fdt_size_cells. It adds a helper function which reads the address and size of a device from the reg property and performs basic sanity checks. It does not perform translation to a physical address using the ranges properties of parents, but this enhancement may be added as a separate function in the future. Signed-off-by: Benjamin Fair <b-fair@xxxxxx> --- The intent of this patch is similar to the commit "libfdt: Add helpers to read #address-cells and #size-cells" [1]. It is related to "libfdt: add address translation support" [2] but does not attempt to perform address translation and was written from scratch rather than reusing GPL code. If the issues with that patch are resolved, that functionality will complement what is added in this patch.
