| | | | | | | | | | | | | | | | | | | | | | | | This change allow to use sd card on Goni the same like mmc 0. SD card is mmc dev 1, so it can be used like this: "fatls mmc 1:2". SD card is inited even if eMMC initialization fails.

* | i2c:samsung: Adjust Trats, GONI and Universal_c210 boards to work with new ↵Łukasz Majewski2013-08-20-14/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I2C framework New I2C framework, introduced after v2013.07 final release, imposed I2C code adjustment for some Samsung boards - namely Trats, GONI and Universal_c210. Those boards were using schematic based I2C enumeration (I2C_5, I2C_9). However, new I2C framework imposes usage of logical I2C adapters numbering (e.g. I2C_0, I2C_1, etc). Additionally, I2C_GET_* macros were replaced with i2c_*_bus_num() functions. Trats board gained definition of second soft I2C adapter.

* arm:samsung:trats:fix: Restore proper orientation of TRATS's LCD panelŁukasz Majewski2013-07-16-9/+1
| | | | | | | | | | | | | | | | | | | | | | | Before setting: mipi_lcd_device.reverse_panel = 1, the Trats's LCD panel was flipped by 180 degrees. The flip was caused by following change: Exynos: Change get_timer() to work correctly SHA1: 3d00c0cb96ff93a929700b80d89cb905e5ab5315 This commit fixed udelay(), which is necessary (due to HW LCD controller oddity) for mipi-dsi correct operation. As a result the display orientation has been switched. As a follow up, the hwrevision() function has been removed, since it was used only in this particular place. Test HW: Trats Exynos4210 rev 0.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch performs the following: 1) Convert the assembly code for memory and clock initialization to C code. 2) Move the memory and clock init codes from board/samsung to arch/arm 3) Creat a common lowlevel_init file across Exynos4 and Exynos5. Converted the common lowlevel_init from assembly to C-code 4) Made spl_boot.c and tzpc_init.c common for both exynos4 and exynos5. 5) Enable CONFIG_SKIP_LOWLEVEL_INIT as stack pointer initialisation is already done in _main. 6) exynos-uboot-spl.lds made common across SMDKV310, Origen and SMDK5250.

| | | | | | | | | | | | | | | | | | | | | | | | Some Exynos5250 silicon may require 1.05v on the MIF to be stable, so to be safe we can default to 1.05v instead of 1.00v. This can be set optimally later in the boot process by the kernel. The 0x6 value for 1.05v comes from the MAX77686 datasheet.

| | | | | | | | | | | | | | | | | | | | | | | | | | This patch enables and initialises DWMMC for SMDK5250. Supports both FDT and non-FDT. This patch creates a new file 'exynos5-dt.c' meant for FDT support. exynos5-dt.c: This file shall contain all code which supports FDT. Any addition of FDT support for any module needs to be added in this file. smdk5250.c: This file shall contain the code which supports non-FDT. version. Any addition of non-FDT support for any module needs to be added in this file. May be, the file smdk5250.c can be removed in near future when non-FDT is not required. The Makefile is updated to compile only one of the files exynos5-dt.c / smdk5250.c based on FDT configuration. NOTE: Please note that all additions corresponding to FDT need to be added into the file exynos5-dt.c. At same time if non-FDT support is required then add the corresponding updations into smdk5250.c. Signed-off-by: Amar <amarendra.xt@samsung.com> Signed-off-by: Minkyu Kang <mk7.kang@samsung.com>

This is a more appropriate symbol naming for an image copy & relocate feature, and this also saves a useless copy of data put between __image_copy_end and __bss_start in linker scripts (e.g. relocation information, or MMU initialization tables used only before jumping to the relocated image).
