[MTD] physmap.c: Add support for multiple resources
This patch extends the physmap mapping driver to support multiple resources for non-identical NOR chips that will be concatenated together when selected. This is needed for example for Intel 48F4400 512MBit chips, since they consist of 2 single different NOR chips with different geometries. The first (lower) one has botton boot sectors and the 2nd (upper) has top boot sectors. This currently isn't handled correctly by calling the physmap driver once with only one resource covering both chips in one memory region. The same geometrie is used for both chips. With this patch the following resource structure can be used to describe the 48F4400 chip correctly: static struct resource board_nor_resource[] = { [0] = { .start = 0xf8000000, .end = 0xfbffffff, .flags = IORESOURCE_MEM, }, [1] = { .start = 0xfc000000, .end = 0xffffffff, .flags = IORESOURCE_MEM, } }; Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
