2014-11-24nitrogen6x: Fix error handling in board_mmc_init()Fabio Estevam
When an invalid USDHC port is passed we should return -EINVAL instead of 0. Also, return the error immediately on fsl_esdhc_initialize() failure. Cc: Eric Nelson <eric.nelson@boundarydevices.com> Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>
2014-10-29kconfig: arm: introduce symbol for ARM CPUsGeorges Savoundararadj
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.

2014-10-06nitrogen6x: display use I2C detect for HDMIEric Nelson
The HPD pin and RX_SENSE registers have proven to be less reliable than using I2C on the EDID pins for detection of an HDMI monitor. In particular, when the HDMI output is reset through a "reboot" cycle, the detect_hdmi() routine often bounces, resulting in a failure to detect a connected monitor.

2014-10-06nitrogen6x: display: add wvga-lvds panelEric Nelson
Add support for WVGA (800x480) panels using VESA GTF timings over LVDS. No auto-detection is supported, so you must configure this panel manually through the 'panel' environment variable: U-Boot > setenv panel svga U-Boot > saveenv && reset Signed-off-by: Eric Nelson <eric.nelson@boundarydevices.com>
2014-10-06nitrogen6x: display: add Ampire 1024x600 panelEric Nelson

2014-10-06nitrogen6x: display: add svga display (800x600)Eric Nelson
Add support for 800x600 18-bit RGB displays using VESA GTF timings. No auto-detection is supported, so you must configure this panel manually through the 'panel' environment variable: U-Boot > setenv panel svga U-Boot > saveenv && reset Signed-off-by: Eric Nelson <eric.nelson@boundarydevices.com>
2014-10-06nitrogen6x: display: add support for fusion 7 displayEric Nelson

2014-10-06nitrogen6x: display: add LDB-WXGA-S for SPWG 1280x800 displaysEric Nelson
This patch adds support for LVDS WXGA displays that use the SPWG encoding standard instead of JEIDA.

2014-10-06nitrogen6x: display: add support for LG-9.7 LVDS displayEric Nelson
Add support for LG 9.7" LVDS panel (1024x768) with integrated eGalax touch screen. Note that this panel differs only slightly from the Hannstar XGA panel (margins). No auto-detection is available because it shares the same touch controller as the Hannstar-XGA display, so you'll need to configure it through the 'panel' environment variable: U-Boot > setenv panel LG-9.7 U-Boot > saveenv && reset Signed-off-by: Eric Nelson <eric.nelson@boundarydevices.com>
2014-10-06nitrogen6x: display: add qvga panelEric Nelson

2014-09-24spi: mxc: fix sf probe when using mxc_spiNikita Kiryanov
MXC SPI driver has a feature whereas a GPIO line can be used to force CS high across multiple transactions. This is set up by embedding the GPIO information in the CS value: cs = (cs | gpio << 8) This merge of cs and gpio data into one value breaks the sf probe command: if the use of gpio is required, invoking "sf probe <cs>" will not work, because the CS argument doesn't have the GPIO information in it. Instead, the user must use "sf probe <cs | gpio << 8>". For example, if bank 2 gpio 30 is used to force cs high on cs 0, bus 0, then instead of typing "sf probe 0" the user now must type "sf probe 15872". This is inconsistent with the description of the sf probe command, and forces the user to be aware of implementaiton details. Fix this by introducing a new board function: board_spi_cs_gpio(), which will accept a naked CS value, and provide the driver with the relevant GPIO, if one is necessary.

Now the types of CONFIG_SYS_{ARCH, CPU, SOC, VENDOR, BOARD, CONFIG_NAME} are specified in arch/Kconfig. We can delete the ones in arch and board Kconfig files. This commit can be easily reproduced by the following command: find . -name Kconfig -a ! -path ./arch/Kconfig | xargs sed -i -e ' /config[[:space:]]SYS_\(ARCH\|CPU\|SOC\|\VENDOR\|BOARD\|CONFIG_NAME\)/ { N s/\n[[:space:]]*string// } ' Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>

2014-07-30Add board MAINTAINERS filesMasahiro Yamada
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.

2014-07-30kconfig: add board Kconfig and defconfig filesMasahiro Yamada
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/.

2014-07-23mx6: Remove duplication of iomuxc structureFabio Estevam
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: Fabio Estevam <fabio.estevam@freescale.com> Acked-by: Stefano Babic <sbabic@denx.de>

Resolution consists in adjusting the list of object files in the main branch version. This also applies to two files which are not listed as conflicting but had to be modified: board/compulab/common/Makefile board/udoo/Makefile include/configs/omap4_common.h conflicts are due to the OMAP4 conversion to ti_armv7_common.h on the ARM side, and CONFIG_SYS_HZ removal on the main side. Resolution is to convert as this icludes removal of CONFIG_SYS_HZ. include/configs/pdnb3.h is due to a removal on ARM side. Trivial resolution is to remove the file. Note: 'git show' will also list two files just because they are new: include/configs/am335x_igep0033.h include/configs/omap3_igep00x0.h

2013-10-31i.MX6: nitrogen6x: fix erase size in 6x_upgrade.txtEric Nelson
The 6x_upgrade script is used to upgrade U-Boot in SPI-NOR on Nitrogen6x/SABRE Lite boards using U-Boot's 'sf' command. U-Boot is placed at offset 0x400 in flash, and the script currently only erases 0x50000 bytes. Since the current head is 319k, any additional features enabled in the configuration will exceed the space erased and cause errors re-programming the device. This patch increases the erase size to the full size of the region allocated for the U-Boot binary.
