* 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.

* am335x_boneblack: Only modify NAND/NOR/MMC1 pinmux on BBB in boneblack builds.Tom Rini2014-10-23-2/+2
| | | | | | | | | | In the case of Beaglebone Black we only want to set the NAND or NOR cape pinmux when the config has been specifically modified by the user for this non-default case. Make the default be to set the MMC1 (eMMC) pinmux. We don't need similar changes for Beaglebone White as there is nothing on MMC1 by default there. Signed-off-by: Tom Rini <trini@ti.com>

* board/ti/am335x: add support for beaglebone NOR Capepekon gupta2014-08-25-60/+35
| | | | | | | | | | | | | This patch adds support of NOR cape[1] for both Beaglebone (white) and Beaglebone(Black) boards. NOR Flash on this cape is connected to GPMC chip-select[0] and accesses as external memory-mapped device. This cape has 128Mbits(16MBytes), x16, CFI compatible NOR Flash device. As GPMC chip-select[0] can be shared by multiple capes so NOR profile is not enabled by default in boards.cfg. Following changes are required to enable NOR cape detection when building am335x_boneblack board profile. Signed-off-by: Tom Rini <trini@ti.com>
* board/ti/am335x: add support for beaglebone NAND capepekon gupta2014-08-25-20/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Beaglebone Board can be connected to expansion boards to add devices to them. These expansion boards are called 'capes'. This patch adds support for following versions of Beaglebone(AM335x) NAND capes (a) NAND Device with bus-width=16, block-size=128k, page-size=2k, oob-size=64 (b) NAND Device with bus-width=16, block-size=256k, page-size=4k, oob-size=224 Further information and datasheets can be found at [1] and [2] * How to boot from NAND using Memory Expander + NAND Cape ? * - Important: As BOOTSEL values are sampled only at POR, so after changing any setting on SW2 (DIP switch), disconnect and reconnect all board power supply (including mini-USB console port) to POR the beaglebone. - Selection of ECC scheme for NAND cape(a), ROM code expects BCH8_HW ecc-scheme for NAND cape(b), ROM code expects BCH16_HW ecc-scheme - Selction of boot modes can be controlled via DIP switch(SW2) present on Memory Expander cape. SW2[SWITCH_BOOT] == OFF follow default boot order MMC-> SPI -> UART -> USB SW2[SWITCH_BOOT] == ON boot mode selected via DIP switch(SW2) So to flash NAND, first boot via MMC or other sources and then switch to SW2[SWITCH_BOOT]=ON to boot from NAND Cape. - For NAND boot following switch settings need to be followed SW2[ 1] = OFF (SYSBOOT[ 0]==1: NAND boot mode selected ) SW2[ 2] = OFF (SYSBOOT[ 1]==1: -- do -- ) SW2[ 3] = ON (SYSBOOT[ 2]==0: -- do -- ) SW2[ 4] = ON (SYSBOOT[ 3]==0: -- do -- ) SW2[ 5] = OFF (SYSBOOT[ 4]==1: -- do -- ) SW2[ 6] = OFF (SYSBOOT[ 8]==1: 0:x8 device, 1:x16 device ) SW2[ 7] = ON (SYSBOOT[ 9]==0: ECC done by ROM ) SW2[ 8] = ON (SYSBOOT[10]==0: Non Muxed device ) SW2[ 9] = ON (SYSBOOT[11]==0: -- do -- ) [1] http://beagleboardtoys.info/index.php?title=BeagleBone_Memory_Expansion [2] http://beagleboardtoys.info/index.php?title=BeagleBone_4Gb_16-Bit_NAND_Module *IMPORTANT NOTE* As Beaglebone board shares the same config as AM335x EVM, so following changes are required in addition to this patch for Beaglebone NAND cape. (1) Enable NAND in am335x_beaglebone board profile (2) Add CONFIG_SYS_NAND_BUSWIDTH_16BIT to board config because: - AM335x EVM has NAND device with datawidth=8, whereas - Beaglebone NAND cape has NAND device with data-width=16
* Add board MAINTAINERS filesMasahiro Yamada2014-07-30-0/+17
| | | | | | | | | | | | | | | | | | | | 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/.

* am335x_evm / gumstix pepper: Correct DDR settingsTom Rini2014-07-25-27/+3
| | | | | | | | | | | | | | As noted by clang, we have been shifting certain values out of 32bit range when setting some DDR registers. Upon further inspection these had been touching reserved fields (and having no impact). These came in from historical bring-up code and can be discarded. Similarly, we had been declaring some fields as 0 when they will be initialized that way. Tested on Beaglebone White.

In all cases, we see if we can rely on the efuse_sma register to tell us the maximum speed. In the case of Beaglebone White, we need to make sure we are on AC power, and are on later than rev A1, and then we can ramp up to the PG1.0 maximum of 720Mhz. In the case of Beaglebone Black, we are either on PG2.0 that supports 1GHz or PG2.1. As PG2.0 may or may not have efuse_sma set, we cannot rely on this probe. In the case of the GP EVM, EVM SK and IDK we need to rely on the efuse_sma if we are on PG2.1, and the defaults for PG1.0/2.0. Signed-off-by: Tom Rini <trini@ti.com>

* am335x_evm: Rework board_is_foo() checksTom Rini2013-07-30-58/+63
| | | | | | | | | | We rework the various board_is_foo() checks to take a pointer to struct am335x_baseboard_id rather than using a local copy in board.c. This allows us to make use of the same checks in mux.c as well as fixing problems when this code could be running from read-only memory.
