* am335x_evm / gumstix pepper: Correct DDR settingsTom Rini2014-07-251-27/+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.

* am335x: Switch to CONFIG_SKIP_LOWLEVEL_INIT from guarding SPL or NOR_BOOTTom Rini2014-04-171-1/+1
| | | | | | | | | | In the case of SPL or NOR_BOOT (no SPL involved) we need to include certain code in the build. Use !CONFIG_SKIP_LOWLEVEL_INIT rather than CONFIG_SPL_BUILD || CONFIG_NOR_BOOT to make the code clearer, and to make supporting XIP QSPI boot clearer in the code.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GPMC controller is common IP to interface with both NAND and NOR flash devices. Also, it supports max 8 chip-selects, which can be independently connected to any of the devices. But ROM code expects the boot-device to be connected to only chip-select[0]. Thus to resolve conflict between NOR and NAND boot. This patch: - combines NOR and NAND configs spread in board files to common gpmc_init() - configures GPMC based on boot-mode selected for SPL boot.

| | | | | | | | | | | | | | | Add a am33xx_spl_board_init (and enable the PMICs) that we may see, depending on the board we are running on. 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: Add support to boot from NOR.Steve Kipisz2013-07-301-4/+29
| | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
