| * board/ls1021aqds: Add DDR4 supportYork Sun2014-09-25-0/+5
| | | | | | | | | | | | | | | | | | | | | | LS1021AQDS has a variant with DDR4 slot. This patch adds a new defconfig for this variant to enable DDR4 support. RAW timing parameters are not added for DDR4. The board timing parameters are only tuned for single- rank 1600 and 1800MT/s with Micron DIMM 9ASF51272AZ-2G1A1 due to DIMM availability.

| * armv8/fsl-lsch3: Release secondary cores from boot hold off with Boot PageYork Sun2014-09-25-89/+518
| | | | | | | | | | | | | | | | | | | | Secondary cores need to be released from holdoff by boot release registers. With GPP bootrom, they can boot from main memory directly. Individual spin table is used for each core. Spin table and the boot page is reserved in device tree so OS won't overwrite.

| * ARMv8/ls2085a_emu: Enable DP-DDR as standalone memory blockYork Sun2014-09-25-1/+2
| | | | | | | | | | | | | | DP-DDR is used for DPAA, separated from main memory pool for general use. It has 32-bit bus width and use a standard DDR4 DIMM (64-bit). Signed-off-by: York Sun <yorksun@freescale.com>
| * driver/ddr: Restruct driver to allow standalone memory spaceYork Sun2014-09-25-2/+2
| | | | | | | | | | | | | | | | | | | | U-boot has been initializing DDR for the main memory. The presumption is the memory stays as a big continuous block, either linear or interleaved. This change is to support putting some DDR controllers to separated space without counting into main memory. The standalone memory controller could use different number of DIMM slots.

| * | powerpc: add --bss-plt to LDFLAGSChris Packham2014-09-25-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With some versions of gcc (that we know of 4.6.3 and 4.8.2 are affected) it is necessary to specify --bss-plt to get the final blrl in the _GOT2_TABLE_. Without this the last symbol does not get it's address relocated. For the P2041RDB board this ended up being NetArpWaitTimerStart which caused the ARP packets to timeout immediately.

Because of that, if by lack of luck 'gd->mon_len = (ulong)&__bss_end - (ulong)_start' (see setup_mon_len()) was a multiple of 4 kiB (see reserve_uboot()), then the last BSS word overlapped the first word of the following reserved RAM area (or went beyond the top of RAM without such an area) after relocation because __image_copy_start did not match _start (see relocate_code()). This was broken by commit 41623c9 'arm: move exception handling out of start.S files', which defined _start twice (before and after the CONFIG_SYS_DV_NOR_BOOT_CFG word), then by commit 0a26e1d 'arm: fix a double-definition error of _start symbol', which kept the definition of the _start symbol after the CONFIG_SYS_DV_NOR_BOOT_CFG word. This new commit fixes this issue by restoring the original behavior, i.e. by defining the _start symbol before the CONFIG_SYS_DV_NOR_BOOT_CFG word.

| * | arm: Make reset position-independentBenoît Thébaudeau2014-09-11-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some boards, like mx31pdk and tx25, require the beginning of the SPL code to be position-independent. For these two boards, this is because they use the i.MX external NAND boot, which starts by executing the first NAND Flash page from the NFC page buffer. The SPL then needs to copy itself to its actual link address in order to free the NFC page buffer and use it to load the non-SPL image from Flash before running it. This means that the SPL runtime address differs from its link address between the reset and the initial copy performed by board_init_f(), so this part of the SPL binary must be position-independent. This requirement was broken by commit 41623c9 'arm: move exception handling out of start.S files', which used an absolute address to branch to the reset routine. This new commit restores the original behavior, which just performed a relative branch. This fixes the boot of mx31pdk and tx25.
