* mmc: i.MX6: fsl_esdhc: Define maximum bus width supported by a boardAbbas Raza2013-04-03-0/+16
| | | | | | | | | | | | | | | | | | Maximum bus width supported by some i.MX6 boards is not 8bit like others. In case where both host controller and card support 8bit transfers, they agree to communicate on 8bit interface while some boards support only 4bit interface. Due to this reason the mmc 8bit default mode fails on these boards. To rectify this, define maximum bus width supported by these boards (4bit). If max_bus_width is not defined, it is 0 by default and 8bit width support will be enabled in host capabilities otherwise host capabilities are modified accordingly. It is tested with a MMCplus card.

| | | | | | | | | | | | | | | | | | | | | | | | | | Currently the following kernel hang happens when loading a 2.6.35 kernel from Freeescale on a mx28evk board: RPC: Registered tcp transport module.

Loading the same kernel using the bootlets from the imx-bootlets-src-10.12.01 package, the hang does not occur. Comparing the DDR2 initialization from the bootlets code against the U-boot one, we can notice some mismatches, and after applying the same initialization into U-boot the 2.6.35 kernel can boot normally.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The pinmux code issues a warning if the caller attempts to disable the lock bit in a pinmux register, since this is impossible (once it's locked, the only way to unlock it is to reset the device/pmt controller). The I2C/DDC/CEC/USB macros expect a lock setting to be passed in, and the previous setting of DISABLE caused the pinmux table parsing code to issue the warning. Changing the lock bits in these table entries to DEFAULT (i.e. don't touch it) fixes this. Signed-off-by: Tom Warren <twarren@nvidia.com> Reviewed-by: Stephen Warren <swarren@nvidia.com>
