* kconfig: arm: introduce symbol for ARM CPUsGeorges Savoundararadj2014-10-29-3/+0
| | | | | | | | | | | | | | | | | 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.

* kconfig: remove redundant "string" type in arch and board KconfigsMasahiro Yamada2014-09-13-5/+0
| | | | | | | | | | | | | | | | | | 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>
* board/ti/am43xx: add support for parallel NANDpekon gupta2014-08-25-1/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for NAND device connected to GPMC chip-select on following AM43xx EVM boards. am437x-gp-evm: On this board, NAND Flash signals are muxed with eMMC, thus at a time either eMMC or NAND can be enabled. Selection between eMMC and NAND is controlled by: (a) Statically using Jumper on connecter (J89) present on board. (a) If Jumper on J89 is NOT used, then selection can be dynamically controlled by driving SPI2_CS0[MUX_MODE=GPIO] pin via software: SPI2_CS0 == 0: NAND (default) SPI2_CS0 == 1: eMMC am43x-epos-evm: On this board, NAND Flash control lines are muxed with QSPI, Thus only one of the two can be used at a time. Selection is controlled by: (a) Dynamically driving following GPIO pin from software GPMC_A0(GPIO) == 0 NAND is selected (default) NAND device (MT29F4G08AB) on these boards has: - data-width=8bits - blocksize=256KB - pagesize=4KB - oobsize=224 bytes For above NAND device, ROM code expects the boot-loader to be flashed in BCH16 ECC scheme for NAND boot, So by default BCH16 ECC is enabled for AM43xx EVMs. Signed-off-by: Pekon Gupta <pekon@ti.com>
* Add board MAINTAINERS filesMasahiro Yamada2014-07-30-0/+7
| | | | | | | | | | | | | | | | | | | | 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.

* kconfig: add board Kconfig and defconfig filesMasahiro Yamada2014-07-30-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | 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/.

| | | | | | | | | | | | | The ePOS EVM and EVM SK have QSPI as an option to boot. Add a qspiboot target that utilizes QSPI for env and so forth as an example of best practices. As QSPI is booted from directly we need to chang CONFIG_SYS_TEXT_BASE. Note that on ePOS EVM the QSPI and NAND are mutually exclusive choices we need to handle that elsewhere, once NAND support is also added.

OPP50 300MHz OPP100 600MHz OPP120 720MHz OPPTB 800MHz OPPNT 1000MHz According to the latest DM following is the OPP table dependencies: VDD_CORE VDD_MPU OPP50 OPP50 OPP50 OPP100 OPP100 OPP50 OPP100 OPP100 OPP100 OPP120 So at different OPPs of MPU it is safest to lock CORE at OPP_NOM.
