2015-01-15arc: move linker script in arch/arc/cpu folderAlexey Brodkin
This way we'll be able to use the same one script for either ARC CPU. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
2015-01-15arc: relocate - minor refactoring and clean-upAlexey Brodkin
* use better symbols for relocatable region boundaries ("__image_copy_start" instead of "CONFIG_SYS_TEXT_BASE") * remove useless debug messages because they will only show up in case of both problem (when normal "if" branch won't be taken) and DEBUG take place which is pretty rare situation.

2015-01-15arc: introduce separate section for interrupt vector tableIgor Guryanov
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.

2015-01-15arc: add dependences on MMU presenceAlexey Brodkin
Depending on MMU presence in CPU there're differences in HW behavior. For example address of instruction that caused exception is put in ECR register if MMU exists and in ERET register otherwise.

2015-01-15arc: interrupts - fix mask setupIgor Guryanov
To disable interrupts we need to reset corresponding flags in STATUS32 register. For this we need to OR flags for interrupts level1 and level2 and then AND with current value in STATUS32. Before that implementation was incorrect. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> Signed-off-by: Igor Guryanov <guryanov@synopsys.com>
2015-01-15arc: add ECR (exception cause register) outputIgor Guryanov
Exception cause register (ECR) contains value that describes a reason for exception that has happened. This helps a lot to figure-out what went wrong. Now we print this register contents when dumping registers. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> Signed-off-by: Igor Guryanov <guryanov@synopsys.com>
2015-01-15arc: check caches existence before useIgor Guryanov
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.

2015-01-14Kconfig: move CONFIG_SYS_CLK_FREQ to KconfigAlexey Brodkin
It makes sense to specify CONFIG_SYS_CLK_FREQ in "configs/xx_defconfig" instead of "include/configs/xxx.h" because then header will be reusable across boards with different CPU clocks. Also this nice to have an ability for end user to tune this value himself via "menuconfig". For now I'm only applying this change to all ARC configs because otherwise scope of change will be huge.

2015-01-14spl: spl_nor: surround Linux-load code with #ifdef CONFIG_SPL_OS_BOOTMasahiro Yamada
If CONFIG_SPL_NOR_SUPPORT is defined, spl_nor_load_image() requires spl_start_uboot(), CONFIG_SYS_OS_BASE, CONFIG_SYS_SPL_ARGS_ADDR, CONFIG_SYS_FDT_BASE to be defined even if users just want to run U-Boot, not Linux.

2015-01-14bootm: Move compression progress/error messages into a functionSimon Glass

2015-01-14lzma: fix buffer bound check error furtherSimon Glass
Commit 4d3b8a0d fixed a problem with lzma decompress where it would run out of bytes to decompress. The algorithm needs to know how many uncompressed bytes it is expected to produce. However, the fix introduced a potential buffer overrun, and causes the compression test to fail (test_compression command in sandbox). The correct fix seems to be to use the minimum of the expected number of uncompressed bytes and the amount of output space available. That way things work normally when there is enough space, and return an error (without overrunning available space) when there is not.

2015-01-14sunxi: axp221: Protect axp221_init against multiple callsHans de Goede
The voltage setting code knows it needs to call axp221_init before calling the various voltage setting functions. But users of axp utility functions like axp221_get_sid() do not know this, so the utility functions always call axp221_init() to ensure that the p2wi / rsb setup magic has been done. Since doing this repeatedly is quite expensive, add a check to axp221_init so that it only does the initialization once.

2015-01-14console: Use pre-console buffer to get complete log on all consolesSiarhei Siamashka
Currently the pre-console buffer can accumulate early log messages and flush them to the serial console as soon as it becomes available. This patch just adds one more pre-console buffer flushing point and does all the same for the other consoles too. This is particularly useful for the vga/hdmi/lcd console, where we can see all the older messages now (except for the log messages from SPL). Naturally, we don't want to get an extra copy of the log messages on the serial console again at the second flushing point, so the serial console has to be explicitly filtered out.
