* arm:am33xx: Rework s_init and add board_early_init_fTom Rini2014-06-06-2/+14
| | | | | | | | | | | With the changes to the i2c framework (and adopting the omap24xx_i2c driver to them) we can no longer call i2c functions prior to gd having been set and cleared. When SPL booting, this is handled by setting gd to point to SRAM in s_init. However in the cases where we are loaded directly by ROM (memory mapped NOR or QSPI) we need to make use of the normal hooks to slightly delay these calls. Signed-off-by: Tom Rini <trini@ti.com>
* arm:am33xx: Make dram_init call sdram_init() in some contextsTom Rini2014-06-06-0/+2
| | | | | | | | | | | | | | | | | We have two contexts for booting these platforms. One is SPL which is roughly: reset, cpu_init_crit, lowlevel_init, s_init, sdram_init, _main, board_init_f from SPL, ... then U-Boot loads. The other is a memory-mapped XIP case (NOR or QSPI) where we do not run an SPL. In this case we go, roughly: reset, cpu_init_crit, lowlevel_init, s_init, _main, regular board_init_f. In the first case s_init will set a valid gd and then be able to call sdram_init which in many cases will need i2c (which needs a valid gd for gd->cur_i2c_bus). In this second case we must (and are able to and should) defer sdram_init() into dram_init() called by board_init_f as gd will have been set in _main and cleared in board_init_f.

* am43xx_evm: Add qspiboot targetSourav Poddar2014-06-06-1/+1
| | | | | | | | | | | | | 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.

* am335x: Switch to CONFIG_SKIP_LOWLEVEL_INIT from guarding SPL or NOR_BOOTTom Rini2014-04-17-3/+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.

* am33xx: Rework #ifdef's around s_init for clarityTom Rini2014-03-12-5/+3
| | | | | | | | | | The s_init function is only called on SPL or XIP cases, so lets only build it for them. This makes the #if logic within the function a bit clearer as to when we are or are not calling things, and makes it easier to see that for example preloader_console_init isn't ever called in the non-XIP full U-Boot case.

* am335x_evm: Add support to boot from NOR.Steve Kipisz2013-07-30-1/+1
| | | | | | | | | | | | | | | | | | 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: Enable RTC 32K OSC clockVaibhav Hiremath2012-10-25-1/+20
| | | | | | | | | | | | | | | | | In order to support low power state, you must source kernel system timers to persistent clock, available across suspend/resume. In case of AM335x device, the only source we have is, RTC32K, available in wakeup/always-on domain. Having said that, during validation it has been observed that, RTC clock need couple of seconds delay to stabilize the RTC OSC clock; and such a huge delay is not acceptable in kernel especially during early init and also it will impact quick/fast boot use-cases. So, RTC32k OSC enable dependency has been shifted to SPL/first-bootloader. Signed-off-by: Vaibhav Hiremath <hvaibhav@ti.com> Signed-off-by: Tom Rini <trini@ti.com>

* SPL: Create arch/arm/lib/spl.c for board_init_f and jump_to_image_linuxTom Rini2012-09-27-0/+2
| | | | | | | | | | | | | | In SPL (CONFIG_SPL_FRAMEWORK) board_init_f must setup the stack pointer, clear the BSS and call board_init_r. We mark this as weak as some platforms may need to perform additional initalization at this point. We provide a gd that we know will be in a usable location, once the BSS has been cleared to help with this as well. Finally, we no longer call relocate_code so remove that from the armv7 version. Next, both board_init_f and jump_to_image_linux are going to be inherently arch-specific, so move these versions to arch/arm/lib/spl.c Signed-off-by: Tom Rini <trini@ti.com>
* SPL: Move the omap SPL framework to common/splTom Rini2012-09-27-1/+1
| | | | | | | | | | | | | Add a new flag, CONFIG_SPL_FRAMEWORK to opt into the common/spl SPL framework, enable on all of the previously using boards. We move the spl_ymodem.c portion to common/ and spl_mmc.c to drivers/mmc/. We leave the NAND one in-place as we plan to replace it later in this series. We use common/spl to avoid linker problems with respect to merging constant strings in objects. Otherwise all strings in common/ will be linked in and kept which grows SPL in size too much.
