* MLK-9665-1 QuadSPI: Support flash bigger than 16MBPeng Fan2014-10-09-1/+50
| | | | | | | | | | | | By introducing CONFIG_SPI_FLASH_BAR and add related command in LUT to enable fsl_qspi.c can handle flash size bigger that 16M. Because uboot does not support 32bits address access, this means bank address should be used to access bigger flash. It is hard to let qspi driver dynamically set LUT, so BRRD BRWR RDEAR and WREAR are all supported. Signed-off-by: Peng Fan <Peng.Fan@freescale.com>

| | | | | | | | | | Currently, flash quad bit is set in "spi_flash_validate_params" and later at the end in the same api, we write 0 to status register for few flashes, thereby overriding the quad bit set.

| | | | | | | | | | | | | | | | Introduce a new configuration "CONFIG_MXC_GPT_HCLK". When it is set, the GPT will use 24Mhz OSC as clock source. Otherwise, the GPT will use 32Khz OSC as clock source. Since only the GPT on iMX6 series provide the clock source option for 24Mhz OSC. For other series(MX5), if the configuration is set, the perclk will be selected as clock source. MX6Q/D Rev 1.0 and MX6SL can't use the 24Mhz OSC clock source option, so select the perclk for them. For MX6SL, we will set the OSC 24Mhz to perclk in CCM, so eventually the clock comes from OSC 24Mhz. Signed-off-by: Ye.Li <B37916@freescale.com>

| | | | | | | | | | | | | | | From i2c spec, if device pull down the SDA line that causes i2c bus dead, host can send out 9 clock to let device release SDA. But for some special device like pfuze100, it pull down SDA line and the solution cannot take effort.

| | | | | | | | | | | | | u-boot v2014 upstream codes have a problem in pfd reset (s_init function) that imx6 Dual is not applied for PLL2 PFD2 reset. It is originated by using dynamical cpu type checking and introducing two cpu types: MXC_CPU_MX6Q and MXC_CPU_MX6D for iMX6 Dual/Quad platform. Fixed this problem by checking the pre_periph_clk_sel and pre_periph2_clk of CCM CBCMR register, if the PLL2 PFD0 or PLL2 PFD2 is used for the clock source, do not reset this PFD to avoid system hang.

When booting from SD/MMC device, change the "mmcroot" to dynamically set according to the boot USDHC controller. It is the same mechanism as "mmcdev" used for kernel image loading. Therefore, the uboot, kernel image, dtb and rootfs are required in same SD/MMC card. To disable the mmc dynamical detection, set the "mmcautodetect" to "no", then "mmcroot" and "mmcdev" will not be overwritten. When booting from other devices which needs to load kernel, dtb and rootfs from SD/MMC card, their "mmcdev" reset vaule is CONFIG_SYS_MMC_ENV_DEV and "mmcroot" reset value is CONFIG_MMCROOT.
