* ARM: AM335x: mux: change mmc0 cd pinmux from mmc0_sdcd to gpioMugunthan V N2015-10-221-1/+1
| | | | | | | | | | Currently omap_hsmmc driver doesn't use sdcd pin to detect whether the card is present or not. Instead the same pin is used as GPIO to detect card presence. So change the pin mux mode from mmc0_sdcd to gpio0_6. Signed-off-by: Mugunthan V N <mugunthanvnm@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com>
* am335x_boneblack: Only modify NAND/NOR/MMC1 pinmux on BBB in boneblack builds.Tom Rini2014-10-231-2/+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 gupta2014-08-251-60/+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 gupta2014-08-251-20/+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

* am335x_evm: Add support to boot from NOR.Steve Kipisz2013-07-301-2/+4
| | | | | | | | | | | | | | | | | | NOR requires that s_init be within the first 4KiB of the image so that we can perform the rest of the required pinmuxing to talk with the rest of NOR that we are found on. When NOR_BOOT is set we save our environment in NOR at 512KiB and a redundant copy at 768KiB. We avoid using SPL for this case and u-boot.bin is written directly to the start of NOR. We enclose the DMM-related parts of arch/arm/cpu/armv7/am33xx/emif4.c with TI81xx checks as at this time U-Boot does not discard unused sections in the main build and this code relies on functions specific to (and only provided in) ti81xx-related code.

* am335x_evm: Add support for the NOR module on the memory capeSteve Kipisz2013-07-301-0/+53
| | | | | | | | | | | This patch adds support for the NOR module that attaches to the memory cape for a Beaglebone board.

* am335x_evm: Rework board_is_foo() checksTom Rini2013-07-301-5/+5
| | | | | | | | | | 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.

* am335x: add initial AM335x IDK board supportMatthias Fuchs2012-11-021-0/+20
| | | | | | | | | | | | | | | | | | This patch extends the am335x_evm board for the AM335x IDK. The IDK board uses MII for the ethernet phy (same as Beaglebone board) and MMC0 for storage (but without card detect line). The IDK uses UART3 for console. So u-boot must be build with CONFIG_SERIAL4 and CONFIG_CONS_INDEX=4 or for the am335x_evm_uart3 board configuration as introduced by Andrew Bradfords recent patch series "am33xx: Enable UART {1,2,3,4,5}...". When using the IDK with console on UART0, those patches are not required. In this case the board slightly needs to be modified. Signed-off-by: Matthias Fuchs <matthias.fuchs@esd.eu>
