* patman: Handle non-ascii characters in namesChris Packham2017-02-081-1/+2
| | | | | | | | | When gathering addresses for the Cc list patman would encounter a UnicodeDecodeError due to non-ascii characters in the author name. Address this by explicitly using utf-8 when building the Cc list. Signed-off-by: Chris Packham <judge.packham@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | | | Add support for version 3 of the ec protocol. It basically works by stitching some additional header in front (special command code), and having a result and packet_length stitched on for the reply.

* dm: core: Replace of_offset with accessorSimon Glass2017-02-08220-407/+445
| | | | | | | | | At present devices use a simple integer offset to record the device tree node associated with the device. In preparation for supporting a live device tree, which uses a node pointer instead, refactor existing code to access this field through an inline function.

* patman: Format checkpatch messages for IDE throwbackSimon Glass2017-02-081-2/+3
| | | | | | | | | | | It is convenient to be able to deal with checkpatch warnings in the same way as build warnings. Tools such as emacs and kate can quickly locate the source file and line automatically. To achieve this, adjust the format to match the C compiler, and output to stderr.

* x86: qemu: Add a config for 64-bit U-BootBin Meng2017-02-074-1/+95
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new board config which uses 64-bit U-Boot. Supported features are the same as the other 64-bit board (Google Chromebook Link). It is a start for us to test 64-bit U-Boot easily without the need to access a real hardware. Note CONFIG_SPL_ENV_SUPPORT is required for QEMU 64-bit as without this the SPL build fails at the end. This is just a workaround as CONFIG_SPL_ENV_SUPPORT is not needed at all. common/built-in.o:(.data.env_htab+0xc): undefined reference to 'env_flags_validate' lib/built-in.o: In function `hsearch_r': lib/hashtable.c:380: undefined reference to 'env_callback_init' lib/hashtable.c:382: undefined reference to 'env_flags_init' make[1]: *** [spl/u-boot-spl] Error 1 Except those SPL options required by 64-bit, compared to 32-bit config, the following options are different: - CONFIG_SYS_MALLOC_F_LEN has to be increased to 0x1000 for SPL. - CONFIG_DEBUG_UART has to be included due to the weird issue. See TODO comments in arch/x86/cpu/x86_64/cpu.c:arch_setup_gd(). Once this issue gets fixed, debug uart can be optional.
