* | | | sunxi: Restore lowlevel_init usageHans de Goede2015-01-21-22/+21
| |/ / |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 2 recent sunxi changes have removed the usage of lowlevel_init by moving some code around and then setting CONFIG_SKIP_LOWLEVEL_INIT. This is problematic for 2 reasons: 1) It does not just stop s_init from being called, it also stops cpu_init_cp15 from getting called, which is undesirable. 2) We want u-boot.bin to be usable standalone, without SPL, some people e.g. use an upstream u-boot.bin together with Allwinner's boot0 loader. So u-boot.bin must (re)initialize the gpios, timer, etc. This commit restores the lowlevel_init / s_init usage, while keeping the changes to no longer use the global-data (gd) struct in the SPL.

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

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.

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>

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.

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.

| * | | | mmc: incomplete test to switch to high-capacity group size definitionsDiego Santa Cruz2015-01-19-22/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
