* fdt_support: delete force argument of fdt_initrd()Masahiro Yamada2014-06-191-1/+1
| | | | | | | | | | | | After all, we have realized "force" argument is completely useless. fdt_initrd() was always called with force = 1. We should always want to do the same thing (set appropriate value to the property) even if the property already exists.

Ever since its introduction in 2003 it is used only in ARM build and always links to same place, so let's simplify the code, remove it and reference directly where needed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After enabling a module, SW has to wait on IDLEST bit until it is Fully functional. This wait is missing for UART module and there is a immediate access of UART registers after this. So there is a chance of hang on this module( This can happen when we are running from MPU SRAM).

| | * arm:am33xx: Rework s_init and add board_early_init_fTom Rini2014-06-061-2/+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 Rini2014-06-062-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a workaround for 32 bit hardware limitation of TDM. T1040 has 36 bit physical addressing, TDM DMAC register are 32 bit wide but need to store address of CCSR space which lies beyond 32 bit address range. This workaround creats a LAW to enable access of TDM DMA to CCSR by mapping CCSR to overlap with DDR. A hole of 16M is created in memory using device tree.
