2012-05-15i.MX28: Shut down the LCD controller before resetMarek Vasut1-1/+8
If the LCD controller is on before the CPU goes into reset, the traffic on LCDIF data pins interferes with the BootROM's boot mode sampling. So shut the controller down.

2012-05-15MX5: PAD_CTL_DRV_VOT_LOW and PAD_CTL_DRV_VOT_HIGH exchangedStefano Babic1-2/+2
After an update to the MX51 reference manual (Rev. 5), the values of the PAD_CTL_DRV_VOT_LOW and PAD_CTL_DRV_VOT_HIGH are now clearly wrong: "Bit 13: High / Low Output Voltage Range. This bit selects the output voltage mode for SD2_CMD. 0 High output voltage mode 1 Low output voltage mode" The values are currently negated in code - fixed.

2012-05-15i.MX28: Add delay after CPU bypass is clearedMarek Vasut1-0/+2
This solves issues when larger amount of DRAM is used, like 256MB. Behave the same in case of CPU bypass as we do in case of EMI bypass, but wait 15 ms. We need to wait until the clock domain stabilizes. This issue seemed to have been caused by not waiting after frobbing with the CPU bypass, it was unrelated to memory, but had a direct impact, causing trouble. This was yet another X-File of the imx-bootlets, sigh. The conclusion is, trying a semi-random delay (there is delay after the EMI bypass change), the issue is fixed. Another possible explanation is that we do not do the "simple memory test" FSL does in their imx-bootlets (1000 R/W cycles to/from piece of the memory, while also outputing something on the serial port). This might have caused the similar delay in the imx-bootlets and therefore they didn't need to add this explicitly. For now, this seems good fix enough, but to me, whole that memory init code in imx-bootlets is completely flunked and it'd need deeper investigation.

FSL 2.6.35 kernel assumes that the bootloader passes the CONFIG_REVISION_TAG information.

On the mx53loco board with mc34708 PMIC it is necessary to turn on VUSB regulator so that the mx53 USBH1 PHY receives the 3.3V voltage. Tested by inserting a USB pen drive in the upper USB slot (USBH1) and then issued the commands: usb start usb info ,which correctly detected and printed the USB pen drive information.

2012-05-15i.MX2: Include asm/types.h in arch-mx25/imx-regs.hTimo Ketola1-0/+3
types.h must be included in imx-regs.h if one wants to include imx-regs.h in a board configuration file. That for one's part is necessary, if one wants to use addresses defined in imx-regs.h. For example, fsl_esdhc.c needs CONFIG_SYS_FSL_ESDHC_ADDR defined and a proper thing is to define it with IMX_MMC_SDHCx_BASE in board configuration file. This patch fixes the build in that case.

2012-05-15Revert "i.MX28: Enable additional DRAM address bits"Marek Vasut1-1/+1
This reverts commit 69d26d09de1cb93e0a09ca71d9f0d41a66f0756a. Apparently, this commit got mainline only because of out-of-tree port and causes breakage on board that is mainline. Revert. Reason: * The OOT board has 512MB of DRAM, enabling this additional address line enabled it to work fine with 512MB of RAM. * Every mainline port has max. 256MB of DRAM, therefore this revert has no impact on any mainline port * Though this caused a problem with new M28 board with 256MB of DRAM where the chips are wired differently. The patch-to-be-reverted caused the DRAM to behave like this: [128MB chunk #1][128MB chunk #1 again][128MB chunk #2][128MB chunk #2 again] Therefore to retain the current one-memory-init-rules-them-all situation, revert this patch until another board emerges and will actually be pushed mainline that needs different setup.
