* Revert "ARM: i.MX: Make NAND related Kconfig options depend on MTD"Lucas Stach2014-12-171-3/+0
| | | | | | | | | | | | | | | | | This reverts commit 4b17d73c7da2, as it is incomplete and partially broken. ARCH_IMX_EXTERNAL_BOOT_NAND does not depend on MTD, it just uses some defines from the mtd/nand header, but does not actually depend on MTD being compiled in. For the other two cases there is a more complete fix merged with commit 57b584d748d4 that also enables the needed MTD write support. Fixes: (MACH_TX25 && MACH_PCA100 && MACH_PCM038) selects ARCH_IMX_EXTERNAL_BOOT_NAND which has unmet direct dependencies (ARCH_IMX && MTD) Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for the Freescale i.MX6sx sabresdb board. Tested are: - UART - The three SD card slots - USB host - USB otg (host and device mode) - FEC (both) Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * ARM: i.MX: Add i.MX6sx supportSascha Hauer2014-11-276-0/+498
| | | | | | | | | | | | | | | | Add some cpu type defines and clock support. The clock support is very different from other i.MX variants, so it's a separate file, like done in the kernel. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * ARM: i.MX: ocotp: Fix MAC address provider for unaligned addressesSascha Hauer2014-11-271-9/+20
| | | | | | | | | | | | | | | | | | | | The current algorithm assumes the MAC address starts at a 4 byte aligned address. Unfortunately this is not always the case. On the i.MX6sx the MAC Address for the second FEC starts at offset 0x632. The register space for the fuse map has holes, only the 16 byte aligned words contain data. This means we have to skip the holes. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * i.MX6: esdctl: Fix a bug in memory probing codeAndrey Smirnov2014-11-201-2/+21
| | | | | | | | | | | | | | | | | | | | | | Old version of imx6_mmdc_add_mem did not use 64-bit arithmetic and thus was prone to overflow on systems with 4GB of memory. It also did not take into account the fact that i.MX6 does not support more than 3.8GB of memory and would report incorrect memory size. This commit fixes both issues.
