2016-06-17arm, am335x: siemens: enable DM/DTS supportHeiko Schocher
enable basic DM/DTS support for the siemens am335x based boards. Signed-off-by: Heiko Schocher <hs@denx.de>
2016-06-09siemens,am33x: add draco etamin boardHeiko Schocher
In the draco CPU board family, etamin is a new variant with bigger flash and more RAM. Due to new flash that uses larger pages (4K) some changes are necessary because it impacts the MTD partition layout and the ubi mount parameters.

2015-08-13kconfig: add config option for shell promptNikita Kiryanov
Add option to set shell prompt string from menuconfig and migrate boards globally. The migration is done as follows: - Boards that explicitly and unconditionally set CONFIG_SYS_PROMPT had the entry moved to their defconfig files. - Boards that defined some kind of #ifdef logic which selects the CONFIG_SYS_PROMPT (for example qemu-mips) got an #undef CONFIG_SYS_PROMPT right before the #ifdef logic and were left alone. - This change forces CONFIG_SYS_PROMPT to be a per board decision, and thus CONFIG_SYS_PROMPT was removed from all <soc>_common.h and <arch>_common.h files. This results in a streamlined default value across platforms, and includes the following files: spear-common, sunxi-common, mv-common, ti_armv7_common, tegra-common, at91-sama5_common, and zynq-common. - Boards that relied on <arch/soc>_common.h values of CONFIG_SYS_PROMPT were not updated in their respective defconfig files under the assumption that since they did not explicitly define a value, they're fine with whatever the default is. - On the other hand, boards that relied on a value defined in some <boards>_common.h file such as woodburn_common, rpi-common, bur_am335x_common, ls2085a_common, siemens_am33x_common, and omap3_evm_common, had their values moved to the respective defconfig files. - The define V_PROMPT was removed, since it is not used anywhere except for assigning a value for CONFIG_SYS_PROMPT.

2015-07-27siemens-am33x-common: Hardcoded value instead of non-included definePaul Kocialkowski
The config file for the siemens-am33x-common was using OMAP_I2C_STANDARD, which is defined in a header that is not included in the config header. In most cases, it was being included by the code using CONFIG_SYS_OMAP24_I2C_SPEED, but it might not always be the case. In particular, when introducing I2C SPL support in omap-common's boot-common.c, the header is missing and including it breaks other devices. Signed-off-by: Paul Kocialkowski <contact@paulk.fr>

Currently in some cases SDRAM init requires global_data to be available and soon this will not be available prior to board_init_f(). Adjust the code paths in these cases to be correct. In some cases we had the SPL stack be in DDR as we might have large stacks (due to Falcon Mode + Environment). In these cases switch to CONFIG_SPL_STACK_R. In other cases we had simply been setting CONFIG_SPL_STACK into SRAM. In these cases we no longer need to (CONFIG_SYS_INIT_SP_ADDR is used and is also in SRAM) so drop those lines.

2013-11-21mtd: nand: omap: add CONFIG_NAND_OMAP_ECCSCHEME for selection of ecc-schemepekon gupta
This patch adds new CONFIG_NAND_OMAP_ECCSCHEME, replacing other distributed CONFIG_xx used for selecting NAND ecc-schemes. This patch aims at solving following issues. 1) Currently ecc-scheme is tied to SoC platform, which prevents user to select other ecc-schemes also supported in hardware. like; - most of OMAP3 SoC platforms use only 1-bit Hamming ecc-scheme, inspite the fact that they can use higher ecc-schemes like 8-bit ecc-schemes with software based error detection (OMAP_ECC_BCH4_CODE_HW_DETECTION_SW). - most of AM33xx SoC plaforms use 8-bit BCH ecc-scheme for now, but hardware supports BCH16 ecc-scheme also. 2) Different platforms use different CONFIG_xx to select ecc-schemes, which adds confusion for user while migrating platforms. - *CONFIG_NAND_OMAP_ELM* which enables ELM hardware engine, selects only 8-bit BCH ecc-scheme with h/w based error-correction (OMAP_ECC_BCH8_CODE_HW) whereas ELM hardware engine supports other ecc-schemes also like; BCH4, and BCH16 (in future). - *CONFIG_NAND_OMAP_BCH8* selects 8-bit BCH ecc-scheme with s/w based error correction (OMAP_ECC_BCH8_CODE_HW_DETECTION_SW). - *CONFIG_SPL_NAND_SOFTECC* selects 1-bit Hamming ecc-scheme using s/w library Thus adding new *CONFIG_NAND_OMAP_ECCSCHEME* de-couples ecc-scheme dependency on SoC platform and NAND driver. And user can select ecc-scheme independently foreach board. However, selection some hardware based ecc-schemes (OMAP_ECC_BCHx_CODE_HW) still depends on presence of ELM hardware engine on SoC.
