* ENGR00315499-10 ARM:imx6:sabresd/sabreauto Add android fastboot supportingNitin Garg2014-06-13-0/+1822
| | | | | | | | | | | | | | | | | | Support android features: fastboot, booti command and recovery for sabresd SD, sabresd eMMC, sabreauto SD, sabreauto NAND. For all booting media (SD, eMMC, NAND), inherits the partitions layout from v2009.08. Fastboot will detect the booting media to replace hardcoding fastboot device. SATA is not supported. FDT is supported to use the "unused" fields in bootimg header which requires the FDT to be combined into the boot.img. For non-FDT boot.img, the "unused" fields should left to NULL and is compatible to boot. Signed-off-by: Ye.Li <B37916@freescale.com> Signed-off-by: Nitin Garg <nitin.garg@freescale.com>

| * mmc: Split mmc struct, rework mmc initialization (v2)Pantelis Antoniou2014-03-24-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The way that struct mmc was implemented was a bit of a mess; configuration and internal state all jumbled up in a single structure. On top of that the way initialization is done with mmc_register leads to a lot of duplicated code in drivers. Typically the initialization got something like this in every driver. struct mmc *mmc = malloc(sizeof(struct mmc)); memset(mmc, 0, sizeof(struct mmc); /* fill in fields of mmc struct */ /* store private data pointer */ mmc_register(mmc); By using the new mmc_create call one just passes an mmc config struct and an optional private data pointer like this: struct mmc = mmc_create(&cfg, priv); All in tree drivers have been updated to the new form, and expect mmc_register to go away before long. Changes since v1: * Use calloc instead of manually calling memset. * Mark mmc_register as deprecated. Signed-off-by: Pantelis Antoniou <panto@antoniou-consulting.com>

* powerpc: mpc8260: consolidate CONFIG_MPC8260 and CONFIG_8260Masahiro Yamada2014-03-07-26/+26
| | | | | | | | | | | | | | | | | | | | | | | Before this commit, CONFIG_MPC8260 and CONFIG_8260 were used mixed-up. All boards with mpc8260 cpu defined both of them: - CONFIG_MPC8260 was defined in board config headers and include/common.h - CONFIG_8260 was defined arch/powerpc/cpu/mpc8260/config.mk We do not need to have both of them. This commit keeps only CONFIG_MPC8260.

* hush: fix some quoted variable expansion issuesStephen Warren2014-03-07-6/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following shell command fails: if test -z "$x"; then echo "zero"; else echo "non-zero"; fi (assuming $x does not exist, it prints "non-zero" rather than "zero"). ... since "$x" expands to nothing, and the argument is completely dropped, causing too few to be passed to -z, causing cmd_test() to error out early. This is because when variable expansions are processed by make_string(), the expanded results are concatenated back into a new string. However, no quoting is applied when doing so, so any empty variables simply don't generate any parameter when the combined string is parsed again. Fix this by explicitly replacing quoting any argument that was originally quoted when re-generating a string from the already-parsed argument list. This also fixes loss of whitespace in commands such as: setenv space " " setenv var " 1${space}${space} 2 " echo ">>${var}<<" Reported-by: Russell King <linux@arm.linux.org.uk> Acked-by: Simon Glass <sjg@chromium.org> Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>

| * arm: Switch to -mno-unaligned-access when supported by the compilerTom Rini2014-02-26-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we tell the compiler to optimize for ARMv7 (and ARMv6 for that matter) it assumes a default of SCTRL.A being cleared and unaligned accesses being allowed and fast at the hardware level. We set this bit and must pass along -mno-unaligned-access so that the compiler will still breakdown accesses and not trigger a data abort. To better help understand the requirements of the project with respect to unaligned memory access, the Documentation/unaligned-memory-access.txt file has been added as doc/README.unaligned-memory-access.txt and is taken from the v3.14-rc1 tag of the kernel.

Before this commit, build process occurred under the source tree for both in-tree and out-of-tree build. That's why we needed to add $(obj) prefix to all generated files in makefiles like follows: $(obj)u-boot.bin: $(obj)u-boot Here, $(obj) is empty for in-tree build, whereas it points to the output directory for out-of-tree build. And our old build system changes the current working directory with "make -C <sub-dir>" syntax when descending into the sub-directories. On the other hand, Kbuild uses a different idea to handle out-of-tree build and directory descending. The build process of Kbuild always occurs under the output tree. When "O=dir/to/store/output/files" is given, the build system changes the current working directory to that directory and restarts the make. Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj=<sub-dir>" syntax for descending into sub-directories. (We can write it like "make $(obj)=<sub-dir>" with a shorthand.) This means the current working directory is always the top of the output directory. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Tested-by: Gerhard Sittig <gsi@denx.de>

* | cmd_test: implement ! on sub-expressionsStephen Warren2014-02-19-19/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, ! can only be parsed as the first operator in an expression. This prevents the following from working: $ if test ! ! 1 -eq 1; then echo yes; else echo no; fi yes $ if test ! 1 -eq 2 -a ! 3 -eq 4; then echo yes; else echo no; fi yes Fix this by parsing ! like any other operator, and and handling it similarly to -a and -o.

* | cmd_test: check for binary operators before unaryStephen Warren2014-02-19-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This better mirrors the behaviour of bash, for example: $ if test -z = -z; then echo yes; else echo no; fi yes This is parsed as a string comparison of "-z" and "-z", since the check for the binary "=" operator occurs first. Without this change, the command would be parsed as a -z test of "-", followed by a syntax error; a trailing -z without and operand. This is a behavioural change, but I believe any commands affected were previously invalid or bizarely formed. Signed-off-by: Stephen Warren <swarren@nvidia.com>
