* MIPS: add support for pre-relocation mallocDaniel Schwierzeck2015-01-21-4/+46
| | | | | | | | | | | Implement MIPS specific setup of the gd_t structure to support pre-relocation malloc. If CONFIG_SYS_MALLOC_F_LEN is specified, a memory area will be reserved after the initial stack area and the gd->malloc_base pointer will be initialized. After this patch the new driver model can be used on MIPS. Signed-off-by: Daniel Schwierzeck <daniel.schwierzeck@gmail.com>

* MIPS: use common code from lib/time.cThomas Langer2015-01-21-110/+8
| | | | | | | | | | | | | The common code just needs the C0_COUNT as free running counter, without the need of writing and checking C0_COMPARE. The function get_tbclk() is still implemented here instead of changing all places of CONFIG_SYS_MIPS_TIMER_FREQ to CONFIG_SYS_TIMER_RATE. The change was tested on a MIPS32 system, but as the MIPS64 code was/is the same, this should be no problem. Signed-off-by: Thomas Langer <thomas.langer@lantiq.com>

* MIPS: bootm: prepare a flattened device tree for the kernelDaniel Schwierzeck2015-01-21-2/+47
| | | | | | | | | | | | Add the initial code to prepare a flattened device tree for the kernel like relocating the FDT blob and fixing up the /chosen and /memory nodes. The final hand over to the kernel is not yet implemented. After the community agreed on the MIPS boot interface for device trees, the corresponding code will be added.

| * arc: rename "arc700" in "arcv1"Alexey Brodkin2015-01-15-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | As a preparation to ARCv2 port submission we rename "arc700" folder to "arcv1" which stands for ARCv1 ISA also known as ARCompact. This will allow us to add more flavours of binary-compatible ARCv1 CPUs like ARC600 if needed later on and all required ARCv2 CPUs (which are binary incompatible with ARCv1) in "arcv2" folder in subsequent commits.

| | | | | | | | | | | | | | | | Both ARCangel4 and AXS10x are FPGA-based boards so they may have different CPUs. For now we have only 1 option (ARC700) and we define this as default in arch Kconfig. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
| * arc: move common sources in libraryAlexey Brodkin2015-01-15-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "reset.c" and "cpu.c" have no architecture-specific code at all. Others are applicable to either ARC CPU. This change is a preparation to submission of ARCv2 architecture port. Even though ARCv1 and ARCv2 ISAs are not binary compatible most of built-in modules still have the same programming model - AUX registers are mapped in the same addresses and hold the same data (new featues extend existing ones). So only low-level assembly code (start-up, interrupt handlers) is left as CPU(actually ISA)-specific. This significantyl simplifies maintenance of multiple CPUs/ISAs.

| * arc: introduce separate section for interrupt vector tableIgor Guryanov2015-01-15-31/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Even though existing implementation works fine in preparation to submission of ARCv2 architecture we need this change. In case of ARCv2 interrupt vector table consists of just addresses of corresponding handlers. And if those addresses will be in .text section then assembler will encode them as everything in .text section as middle-endian and then on real execution CPU will read swapped addresses and will jump into the wild. Once introduced new section is situated so .text section remains the first which allows us to use common linker option for linking everything to a specified CONFIG_SYS_TEXT_BASE.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some cache operations ({i|d}cache_{enable|disable|status} or flush_dcache_all) are built and used even if CONFIG_SYS_{I|D}CACHE_OFF is set. This is required for force disable of caches on early boot. What if something was executed before U-boot and enabled caches (low-level bootloaders, previously run kernel etc.)? But if CPU doesn't really have caches any attempt to access cache-related AUX registers triggers instruction error exception. So for convenience we'll try to avoid exceptions by checking if CPU actually has caches (we check separately data and instruction cache existence) at all.

| * | mmc: Skip changing bus width for MMC cards earlier than version 4.0Andrew Gabbasov2015-01-19-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Wider bus widths (larger than default 1 bit) appeared in MMC standard version 4.0. So, for MMC cards of any earlier version trying to change the bus width (including ext_csd comparison) does not make any sense. It may work incorrectly and at least cause unnecessary timeouts. So, just skip the entire bus width related activity for earlier versions. Signed-off-by: Andrew Gabbasov <andrew_gabbasov@mentor.com> Tested-by: Alexey Brodkin <abrodkin@synopsys.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If all the commands switching an MMC card to 4- or 8-bit bus width fail, and the bus width for the controller and the driver is still set to default 1 bit, there is no need to send one more command to switch the card to 1-bit bus width. Also, if the card or host controller do not support wider bus widths, there is no need to send a switch command at all. However, if one of switch commands succeeds, but the subsequent ext_csd fields comparison fails, the card should be switched to some other bus width (next in the list for the loop), or to default 1-bit bus width as a last resort. That's why it would be incorrect to just remove the 1-bit bus width case from the list, it should still be processed in some cases. panto: Minor cosmetic edit removing superfluous parentheses.

The new mmc_hwpart_config() function does the partitioning in one go. As the different attributes and partitioning options on eMMC may be interdependent validation has to be done based on the complete partitioning configuration. The function accepts three modes: - MMC_HWPART_CONF_CHECK: just validates that the configuration is valid. - MMC_HWPART_CONF_SET: validates and sets all the fields in EXT_CSD but without setting the "partitioning completed" bit, and thus is reversible. - MMC_HWPART_CONF_COMPLETE: does everything and is thus not reversible.

| * | mmc: eMMC partitioning data is not effective till partitioning completedDiego Santa Cruz2015-01-19-23/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The eMMC spec says that partitioning is only effective after the PARTITION_SETTING_COMPLETED is set in EXT_CSD (and a power cycle was done, but that we cannot know). Thus the partition sizes and attributes should be ignored when that bit is not set, otherwise the various capacities are not coherent (e.g., the user data capacity will be that of the unpartitioned device while partition sizes would be non-zero). Prescence of non-zero partitioning data is nevertheless still used to activate the high-capacity size definitions (EXT_CSD_ERASE_GROUP_DEF) as it is necessary to set that to write any of the partitioning fields in EXT_CSD, so having partitioning data means someone previously activated that and we should keep it activated.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The eMMC spec mandates that the high-capacity group size definitions should be enabled when the device is partitioned (by setting ERASE_GROUP_DEF in EXT_CSD). The current test to determine when this is required misses a few cases. In particular a device may have been partitioned without setting the enhanced attribute on any partition or partitioning may be completed without creating any extra partitions. This change moves the code to set ERASE_GROUP_DEF to after reading all partition information. It is also enabled when PARTITIONING_SETTING_COMPLETED is set as it is necessary to enable ERASE_GROUP_DEF before setting that bit, so it means that the user previously switched to the high capacity definitions.

Factor the musb reset code into a usb_reset_root_port function (and add this as an empty define for other controllers), and call this when a device has no parent. 2) Just like with normal usb controllers there needs to be a delay after reset, for normal usb controllers, this is handled in hub_port_reset, add a delay to usb_reset_root_port. 3) Sync the musb reset sequence with the upstream kernel, clear all bits of power except bits 4-7, and increase the time reset is asserted to 50 ms.
