* dm: fdt: Add a function to decode phandles with argumentsSimon Glass2015-01-29-0/+124
| | | | | | | | | | | For GPIOs and other functions we want to look up a phandle and then decode a list of arguments for that phandle. Each phandle can have a different number of arguments, specified by a property in the target node. This is the "#gpio-cells" property for GPIOs. Add a function to provide this feature, taken modified from Linux 3.18. Signed-off-by: Simon Glass <sjg@chromium.org>

* lzma: fix buffer bound check error furtherSimon Glass2015-01-14-2/+2
| | | | | | | | | | | | | | | | | | | | | | 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.

| * ARM: tegra: Implement XUSB pad controllerThierry Reding2014-12-18-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This controller was introduced on Tegra114 to handle XUSB pads. On Tegra124 it is also used for PCIe and SATA pin muxing and PHY control. Only the Tegra124 PCIe and SATA functionality is currently implemented, with weak symbols on Tegra114. Tegra20 and Tegra30 also provide weak symbols for these functions so that drivers can use the same API irrespective of which SoC they're being built for.

* | initcall: add explicit hint if initcall was relocatedAlexey Brodkin2014-12-29-1/+5
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit "initcall: Improve debugging support" makes sense and indeed simplifies process of matching initcalls executed with static disassembly. Until you are debugging relocation functionality. Existign output may make you think that at some point execution somehow returned back to non-relocated area. And there're many reasons/problems that may provoke this behavior. In order to make things clear let's add explicit mention in case initall was actually relocated like this: --->--- initcall: 810015f8 Relocation Offset is: 0efcf000 Relocating to 8ffcf000, new gd at 8fdced3c, sp at 8fdced20 initcall: 810015b8 initcall: 8ffd093c initcall: 8ffd0a14 initcall: 81001940 (relocated to 8ffd0940) initcall: 81001958 (relocated to 8ffd0958) --->--- Note "unexpected" jump from 0x8f... area to 0x81... area. Without explanation this raises many questions: execution jumped in relocated area right as expected and then for some reason returned back? But I hope comment in brackets will save some time for those curious developers who are careful enough to catch "unexpected jump to pre-reloc area" or those unlucky ones who'll have to deal with relocation debugging.

This also needs the Intel Management Engine (me.bin) to work. Binary blobs everywhere: so far we have MRC, ME and microcode. SDRAM init works by setting up various parameters and calling the MRC. This in turn does some sort of magic to work out how much memory there is and the timing parameters to use. It also sets up the DRAM controllers. When the MRC returns, we use the information it provides to map out the available memory in U-Boot. U-Boot normally moves itself to the top of RAM. On x86 the RAM is not generally contiguous, and anyway some RAM may be above 4GB which doesn't work in 32-bit mode. So we relocate to the top of the largest block of RAM we can find below 4GB. Memory above 4GB is accessible with special functions (see physmem). It would be possible to build U-Boot in 64-bit mode but this wouldn't necessarily provide any more memory, since the largest block is often below 4GB. Anyway U-Boot doesn't need huge amounts of memory - even a very large ramdisk seldom exceeds 100-200MB. U-Boot has support for booting 64-bit kernels directly so this does not pose a limitation in that area. Also there are probably parts of U-Boot that will not work correctly in 64-bit mode. The MRC is one. There is some work remaining in this area. Since memory init is very slow (over 500ms) it is possible to save the parameters in SPI flash to speed it up next time. Suspend/resume support is not fully implemented, or at least it is not efficient. With this patch, link boots to a prompt. Signed-off-by: Simon Glass <sjg@chromium.org>

The %pa modifier is used for this purpose, so phys_addr_t variables need to be passed by reference, like so: phys_addr_t start = 0; printf("start: %pa\n", &start); Depending on the size of phys_addr_t this will print out the address with 8 or 16 hexadecimal digits following a 0x prefix.

Moreover, we are suffering from too cluttered include/common.h. This commit moves various macros that originate in include/linux/kernel.h of Linux to their original position.
