| * spi: mxc_spi: Fix ECSPI reset handlingDirk Behme2013-04-04-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Reviewing the ECSPI reset handling shows two issues: 1. For the enable/reset bit (MXC_CSPICTRL_EN) in the control reg (ECSPIx_CONGREG) the i.MX6 technical reference manual states: -- cut -- ECSPIx_CONREG[0]: EN: Writing zero to this bit disables the block and resets the internal logic with the exception of the ECSPI_CONREG. -- cut -- Note the exception mentioned: The CONREG itself isn't reset. Fix this by manually writing the reset value 0 to the whole register. This sets the EN bit to zero, too (i.e. includes the old ~MXC_CSPICTRL_EN). 2. We want to reset the whole SPI block here. So it makes no sense to first read the old value of the CONREG and write it back, later. This will give us the old (historic/random) value of the CONREG back. And doesn't reset the CONREG. To get a clean CONREG after the reset of the block, too, don't use the old (historic/random) value of the CONREG while doing the reset. And read the clean CONREG after the reset. This was found while working on a SPI boot device where the i.MX6 boot ROM has already initialized the SPI block. The initialization by the boot ROM might be different to what the U-Boot driver wants to configure. I.e. we need a clean reset of SPI block, including the CONREG.

| * i.MX6: mx6qsabrelite: README: don't pass chip-select to sf probe commandJavier Martinez Canillas2013-04-03-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | board/freescale/mx6qsabrelite/README explain a procedure to update the SPI-NOR on the SabreLite board without Freescale manufacturing tool but following this procedure leads to both "sf erase" and "sf write" failing on a mx6qsabrelite board: MX6QSABRELITE U-Boot > sf probe 1 MX6QSABRELITE U-Boot > sf erase 0 0x40000 SPI flash erase failed MX6QSABRELITE U-Boot > sf write 0x10800000 0 0x40000 SPI flash write failed This is because the chip-select 1 is wrong and the correct value is 0x7300. Since commit c1173bd0 ("sf command: allow default bus and chip selects") the chip-select and bus arguments for the sf probe command are optional so let's just remove it and use "sf probe" instead.

| * mx6: Fix get_board_rev() for the mx6 solo caseFabio Estevam2013-04-03-20/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When booting a Freescale kernel 3.0.35 on a Wandboard solo, the get_board_rev() returns 0x62xxx, which is not a value understood by the VPU (Video Processing Unit) library in the kernel and causes the video playback to fail. The expected values for get_board_rev are: 0x63xxx: For mx6quad/dual 0x61xxx: For mx6dual-lite/solo So adjust get_board_rev() accordingly and make it as weak function, so that we do not need to define it in every mx6 board file.

| * 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. RPC: Registered tcp NFSv4.1 backchannel transport module. Bus freq driver module loaded IMX usb wakeup probe usb h1 wakeup device is registered mxs_cpu_init: cpufreq init finished ... 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. Also tested with 'mtest' command, which runs succesfully.
