Currently MX6 SPL DDR initialization hardcodes the REF_SEL and REFR fields of the MDREF register as 1 and 7, respectively for DDR3 and 0 and 3 for LPDDR2. Looking at the MDREF initialization done via DCD we see that boards do need to initialize these fields differently: $ git grep 0x021b0020 board/ board/bachmann/ot1200/mx6q_4x_mt41j128.cfg:DATA 4 0x021b0020 0x00005800 board/ccv/xpress/imximage.cfg:DATA 4 0x021b0020 0x00000800 /* MMDC0_MDREF */ board/freescale/mx6qarm2/imximage.cfg:DATA 4 0x021b0020 0x7800 board/freescale/mx6qarm2/imximage.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qarm2/imximage_mx6dl.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qarm2/imximage_mx6dl.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qsabreauto/imximage.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qsabreauto/mx6dl.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6qsabreauto/mx6qp.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6sabresd/mx6dlsabresd.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6sabresd/mx6q_4x_mt41j128.cfg:DATA 4 0x021b0020 0x00005800 board/freescale/mx6slevk/imximage.cfg:DATA 4 0x021b0020 0x00001800 board/freescale/mx6sxsabreauto/imximage.cfg:DATA 4 0x021b0020 0x00000800 board/freescale/mx6sxsabresd/imximage.cfg:DATA 4 0x021b0020 0x00000800 board/warp/imximage.cfg:DATA 4 0x021b0020 0x00001800 So introduce a mechanism for users to be able to configure REFSEL and REFR fields as needed. Keep all the mx6 SPL users in their current REF_SEL and REFR values, so no functional changes for the existing users. Signed-off-by:

This patch adds basic support for the SolidRun ClearFog Armada 38x based board to mainline U-Boot. Supported interfaces / devices are: - DDR3 - UART - MMC - Ethernet port 0 (connected to dedicated PHY) - I2C The included DT source was taken from Russell King's ftp server: http://www.home.arm.linux.org.uk/~rmk/clearfog/ With only minor modifications, like the addition of some aliases and the "u-boot,dm-pre-reloc" property.

Since commit 59370f3f ("net: phy: delay only if reset handler is registered") Ethernet is no longer functional: Booting from net ... FEC Waiting for PHY auto negotiation to complete......... TIMEOUT ! BOOTP broadcast 1 BOOTP broadcast 2 BOOTP broadcast 3 BOOTP broadcast 4 This commit does not have an issue in itself, but it revelead a problem with the Ethernet initialization. As per the AR8035 datasheet: "For a reliable power on reset, suggest to keep asserting the reset low long enough (10ms) to ensure the clock is stable and clock-to-reset 1ms requirement is satisfied." So do as suggested and keep the reset low for 10ms. Also add a 100us delay after deasserting the reset line to guarantee that the PHY ID can be read correctly and the Atheros PHY can be loaded as per Troy Kisky's suggestion. Signed-off-by:

To i.MX6, DDR3 and LPDDR2 is supported, so rename function mx6_dram_cfg to mx6_ddr3_cfg and the original mx6_dram_cfg function only is a wrapper. The new reimplemented function mx6_dram_cfg only invokes mx6_ddr3_cfg when ddr_type is for DDR3. Later we can use ddr_type to initialize MMDC for LPDDR2. Initialize ddr_type for different boards which enable SPL. Signed-off-by:

mx6cuboxi sometimes fails to recognize the Ethernet PHY: Net: Phy 0 not found The explanation for this behavior comes from from Rabeeh Khoury: "The LED_ACT pin on the carrier-one boards had a pull down that forces the phy address to 0x0; where on CuBox-i and the production HummingBoard that pin is connected directly to LED that depending on the pull down strength of the LED it might be sampled as '0' or '1' thus the phy address might appear as either address 0x0 or 0x4." "This is AR8035 implementation; in reset stage the LED pin is configured as input, and pull up/down does matter. In this case it configures the PHY address. After reset is deasserted the same LED pin becomes output and then according to the previous pull/up it should be active high/low" One way to properly fix this behavior is to place external pull-up/down resistors in the LED line, but from a software standpoint we can fix it by telling phy_find_by_mask() to scan the PHY at addresses 0x0 and 0x4.

This commit introduces a Kconfig symbol for each ARM CPU: CPU_ARM720T, CPU_ARM920T, CPU_ARM926EJS, CPU_ARM946ES, CPU_ARM1136, CPU_ARM1176, CPU_V7, CPU_PXA, CPU_SA1100. Also, it adds the CPU feature Kconfig symbol HAS_VBAR which is selected for CPU_ARM1176 and CPU_V7. For each target, the corresponding CPU is selected and the definition of SYS_CPU in the corresponding Kconfig file is removed. Also, it removes redundant "string" type in some Kconfig files.

We have switched to Kconfig and the boards.cfg file is going to be removed. We have to retrieve the board status and maintainers information from it. The MAINTAINERS format as in Linux Kernel would be nice because we can crib the scripts/get_maintainer.pl script. After some discussion, we chose to put a MAINTAINERS file under each board directory, not the top-level one because we want to collect relevant information for a board into a single place. TODO: Modify get_maintainer.pl to scan multiple MAINTAINERS files. Signed-off-by:

This commit adds: - arch/${ARCH}/Kconfig provide a menu to select target boards - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig set CONFIG macros to the appropriate values for each board - configs/${TARGET_BOARD}_defconfig default setting of each board (This commit was automatically generated by a conversion script based on boards.cfg) In Linux Kernel, defconfig files are located under arch/${ARCH}/configs/ directory. It works in Linux Kernel since ARCH is always given from the command line for cross compile. But in U-Boot, ARCH is not given from the command line. Which means we cannot know ARCH until the board configuration is done. That is why all the "*_defconfig" files should be gathered into a single directory ./configs/. Signed-off-by:

There is no need to keep iomuxc_base_regs structure as it serves the exact same purpose of the iomuxc structure, which is to provide access to the GPR registers. The additional fields of iomuxc_base_regs are not used. Other advantage of 'iomuxc' is that it has a shorter name and the variable declarations can fit into a single line. So remove iomuxc_base_regs structure and use iomuxc instead. Signed-off-by:
