This patch - consolidate CONFIG_SYS_NAND_xx and CONFIG_SPL_NAND_xx from various configuration files into single file. - update MTD Partition table to match AM335x_EVM DT in linux-kernel - segregate CONFIGs based on different boot modes (like SPL and U-Boot)

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 -- )

*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

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. diff --git a/boards.cfg b/boards.cfg -Active arm armv7 am33xx ti am335x am335x_boneblack am335x_evm:SERIAL1,CO +Active arm armv7 am33xx ti am335x am335x_boneblack am335x_evm:SERIAL1,CO

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.

This patch adds support for x16 NAND device (MT29F2G16AAD) connected to GPMC chip-select[0] on DRA7xx EVM. As GPMC pins are shared by multiple devices, so in addition to this patch following board settings are required for NAND device detection [1]:

This patch adds support for parallel NOR device (S29GL512S10) present on J6-EVM. The Flash device is connected to GPMC controller on chip-select[0] and accessed as memory-mapped device. It has data-witdh=x16, capacity-64MBytes(512Mbits) and is CFI compatible.

As multiple devices are share GPMC pins on this board, so following board settings are required to detect NOR device: SW5.1 (NAND_BOOTn) = OFF (logic-1) SW5.2 (NOR_BOOTn) = ON (logic-0) /* Active-low */ SW5.3 (eMMC_BOOTn) = OFF (logic-1) SW5.4 (QSPI_BOOTn) = OFF (logic-1)

And also set appropriate SYSBOOT configurations: SW3.1 (SYSBOOT[ 8])= ON (logic-1) /* selects SYS_CLK1 speed */ SW3.2 (SYSBOOT[ 9])= OFF (logic-0) /* selects SYS_CLK1 speed */ SW3.3 (SYSBOOT[10])= ON (logic-1) /* wait-pin monitoring = enabled */ SW3.4 (SYSBOOT[11])= OFF (logic-0) /* device type: Non Muxed */ SW3.5 (SYSBOOT[12])= OFF (logic-0) /* device type: Non Muxed */ SW3.6 (SYSBOOT[13])= ON (logic-1) /* device bus-width: 1(x16) */ SW3.7 (SYSBOOT[14])= OFF (logic-0) /* reserved */ SW3.8 (SYSBOOT[15])= ON (logic-1) /* reserved */
