| | | | | | | | | | | | 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.

* MX5: PAD_CTL_DRV_VOT_LOW and PAD_CTL_DRV_VOT_HIGH exchangedStefano Babic2012-05-15-2/+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.

* i.MX28: Add delay after CPU bypass is clearedMarek Vasut2012-05-15-0/+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.

* mx53loco: Add CONFIG_REVISION_TAGFabio Estevam2012-05-15-0/+5
| | | | | | | | | | | FSL 2.6.35 kernel assumes that the bootloader passes the CONFIG_REVISION_TAG information. The kernel uses this data to distinguish between Dialog versus mc34708 based boards, and also to distinguish between revA and revB of the mc34708 based boards.

* i.MX2: Include asm/types.h in arch-mx25/imx-regs.hTimo Ketola2012-05-15-0/+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.

This is a workaround to fix some memory clock jitter. Note: This should be but can't be done in the DCD. The bootloader prevents access to the ANATOP registers.

* Revert "i.MX28: Enable additional DRAM address bits"Marek Vasut2012-05-15-1/+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.

* MX53: add function to set SATA clock to internalStefano Babic2012-05-15-0/+25
| | | | | | | | | | | | | | | | | | | | | The MX53 SATA interface can use an internal clock (USB PHY1) instead of an external clock. This is an undocumented feature, but used on most Freescale's evaluation boards, such as MX53-loco. As stated by Freescale's support: Fuses (but not pins) may be used to configure SATA clocks. Particularly the i.MX53 Fuse_Map contains the next information about configuring SATA clocks : SATA_ALT_REF_CLK[1:0] (offset 0x180C) '00' - 100MHz (External) '01' - 50MHz (External) '10' - 120MHz, internal (USB PHY) '11' - Reserved Signed-off-by: Stefano Babic <sbabic@denx.de> CC: Fabio Estevam <fabio.estevam@freescale.com>
