* MLK-10957: ARM: mx6qp: do not turn off PURobin Gong2015-07-31-1/+2
| | | | | | | | | There is narrow window that PRE driver is ready but GPU driver probe later, and the later GPU driver turn on PU may cause 'PRE hang' issue. To simplify thing, do not turn off PU in u-boot. Signed-off-by: Robin Gong <b38343@freescale.com> (cherry picked from commit 6b0787b726e2ff32210d742d93ecd3f4bb2ae402)
* MLK-11304 MX6 SabreSD: Disable HDMI detectPeng Fan2015-07-31-1/+1
| | | | | | | | | | | | | | | As the HDMI splash screen feature is not well supported, we should not set it to be the default display. In case, users leave the 'panel' uboot environment variable empty and connect the board with a HDMI monitor, the HDMI detect funtion will work and enable the HDMI splash screen. So, this patch disables HDMI detect function so that users may only explicitly set the 'panel' variable to be 'HDMI' to use HDMI splash screen.

| | | | | | | | | The bootargs is not set correctly. The final bootargs consist of uboot's bootargs and bootimg's bootargs. This patch set bootimg's bootargs as final bootargs if uboot's bootargs is not set. And take uboot's bootargs as final bootargs if uboot's bootargs is set.

* MLK-11238 imx: mx7d fix usdhc pad settingsPeng Fan2015-07-13-35/+24
| | | | | | | | | | | | | | | | | | | To CD/VSELECT/RST, should use same pad settings with USDHC_PAD_CTRL, because default NO_PAD_CTRL's settings is 100K Pull-Down. But, we need pull-up for CD/VSELECT/RST. Also some board provides external pull-down/up, we'd better use internal pull-up for these pad settings. To mx7d_12x12_lpddr3_arm2: If no card plugged in, "mmc dev 1" will show "Card did not respond to voltage select". After apply this patch, it will show "MMC: no card present". To mx7dsabresd: Alougth without this patch, if no card plugged in sd1, still correct msg "MMC: no card present", anyway we'd better use pull-up. Signed-off-by: Peng Fan <Peng.Fan@freescale.com>

Change the booti command to boota, due to the booti has been used for ARM64 image boot. 5. Modify boota implementation to load ramdisk and fdt to their loading addresses specified in boot.img header, while bootm won't do it for android image. 6. Modify the android image HAB implementation. Authenticate the boot.img on the "load_addr" for both SD and NAND. 7. Enable new configuration CONFIG_FSL_FASTBOOT for Freescale's fastboot with relevant header file "fsl_fastboot.h".

| | | | | | | | | | | | | | | | | | | | | On MX7D, boot rom can provide some boot information such as boot device, arm freq, axi freq, etc. (see the structure below) Offset Byte4 | Byte3 | Byte2 | Byte1 0x0 Reserved | Boot Device Type | Boot Device Instance | Reserved 0x4 ARM core frequency(in Hz) 0x8 AXI bus frequency(in Hz) 0x0C DDR frequency(in Hz) 0x10 GPT1 input clock frequency(in Hz) 0x14 Reserved 0x18 0x1C The boot information can be accessed by get the pointer at 0x1E8. This patch changes the u-boot to use the new approach. When manufacture boot, the info recorded is the actual SD port, not the failed device. Signed-off-by: Ye.Li <B37916@freescale.com>
