* Add 64-bit data support for memory commandsYork Sun2014-03-04-10/+151
| | | | | | | | | | Add 64-bit data for memory commands, such as md, mw, mm, cmp. The new size ".q " is introduced. For 64-bit architecture, 64-bit data is enabled by default, by detecting compiler __LP64__. It is optional for other architectures. Signed-off-by: York Sun <yorksun@freescale.com>
* dm: Enable gpio command to support driver modelSimon Glass2014-03-04-13/+116
| | | | | | | | | | Now that named GPIO banks are supported, along with a way of obtaining the status of a GPIO (input or output), we can provide an enhanced GPIO command for driver model. Where the driver provides its own operation for obtaining the GPIO state, this is used, otherwise a generic version is sufficient. Signed-off-by: Simon Glass <sjg@chromium.org>

To use these with driver model, define CONFIG_CMD_DEMO and CONFIG_DM_DEMO. The two demo drivers are enabled with CONFIG_DM_DEMO_SIMPLE and CONFIG_DM_DEMO_SHAPE.

* Add cmd_process_error() to report and process errorsSimon Glass2014-03-04-0/+10
| | | | | | | | | | | | U-Boot now uses errors defined in include/errno.h which are negative integers. Commands which fail need to report the error and return 1 to indicate failure. Add this functionality in cmd_process_error(). For now this merely reports the error number. It would be possible also to produce a helpful error message by storing the error strings in U-Boot.

| * 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.

This commit disables temporary scripts: scripts/{Makefile.build.tmp, Makefile.host.tmp} and enables real Kbuild scripts: scripts/{Makefile.build,Makefile.host,Makefile.lib}. This switch is triggered by the line in scripts/Kbuild.include -build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj +build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj We need to adjust some build scripts for U-Boot. But smaller amount of modification is preferable. Additionally, we need to fix compiler flags which are locally added or removed. In Kbuild, it is not allowed to change CFLAGS locally. Instead, ccflags-y, asflags-y, cppflags-y, CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o are prepared for that purpose.

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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* | cmd_test: use table lookup for parsingStephen Warren2014-02-19-67/+110
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | do_test() currently uses strcmp() twice to determine which operator is present; once to determine how many arguments the operator needs, then a second time to actually decode the operator and implement it. Rewrite the code so that a table lookup is used to translate the operator string to an integer, and use a more efficient switch statement to decode and execute the operator. This approach also acts as enablement for the following patches. This patch should introduce no behavioural change. Signed-off-by: Stephen Warren <swarren@nvidia.com>

* | pxe: support "devicetree" tagStephen Warren2014-02-04-0/+1
|/ | | | | | | | | The specification for extlinux.conf[1] states that "fdt" is an alias for "devicetree". To date, U-Boot only implements "fdt". Rectify that. [1] http://freedesktop.org/wiki/Specifications/BootLoaderSpec/ Signed-off-by: Stephen Warren <swarren@nvidia.com>
* board_r - fixup functions table after relocationAlexey Brodkin2014-01-27-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | This is only required for "PIC" relocation and doesn't apply to modern "PIE" relocation which does data relocation as well as code. "init_sequence_r" is just an array that consists of compile-time adresses of init functions. Since this is basically an array of integers (pointers to "void" to be more precise) it won't be modified during relocation - it will be just copied to new location as it is. As a consequence on execution after relocation "initcall_run_list" will be jumping to pre-relocation addresses. As long as we don't overwrite pre-relocation memory area init calls are executed correctly. But still it is dangerous because after relocation we don't expect initially used memory to stay untouched.
