| | | | | | | | | Fix H-PLL and M-PLL rate calculation in ast2500 clock driver. Without this fix, valid setting can lead to division by zero when requesting the rate of H-PLL or M-PLL clocks. Signed-off-by: Maxim Sloyko <maxims@google.com> Reviewed-by: Simon Glass <sjg@chromium.org>
* cmd: gpt: backup boot code before writing MBRVincent Tinelli2017-02-08-0/+7
| | | | | | | | | | | | | On some cases the first 440 bytes of MBR are used to keep an additional information for ROM boot loader. 'gpt write' command doesn't preserve that area and makes boot code gone. Preserve boot code area when run 'gpt write' command.

* cmd: rework "license" commandMasahiro Yamada2017-02-08-66/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous commit ("add a new command to show .config contents") improves the basic infrastructure of "embed a compressed file into the U-Boot image, and print it by a command". The same pattern for the "license" command. This commit reworks the command to improve the following: [1] Improve log style Kbuild style log GZIP cmd/license_data.gz CHK cmd/license_data_gz.h UPD cmd/license_data_gz.h CHK cmd/license_data_size.h UPD cmd/license_data_size.h instead of the bare Make log: cat ./Licenses/gpl-2.0.txt | gzip -9 -c | \ tools/bin2header license_gzip > ./include/license.h [2] Collect related code into the "cmd" directory Prior to this commit, the license.h was created by tools/Makefile, placed under the "include" directory, included from cmd/license.c, and deleted by the top-level Makefile. It is not a good idea to scatter related code. [3] Drop the fixed-malloc size LICENSE_MAX Just allocate the minimum required size of buffer because we know the size of the original gpl-2.0.txt. [4] Fix more issues Terminate the buffer with zero to prevent puts() from over-running. Add "static" to do_license.

* cmd: add a new command "config" to show .config contentsMasahiro Yamada2017-02-08-5/+97
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This feature is inspired by /proc/config.gz of Linux. In Linux, if CONFIG_IKCONFIG is enabled, the ".config" file contents are embedded in the kernel image. If CONFIG_IKCONFIG_PROC is also enabled, the ".config" contents are exposed to /proc/config.gz. Users can do "zcat /proc/config.gz" to check which config options are enabled on the running kernel image. The idea is almost the same here; if CONFIG_CMD_CONFIG is enabled, the ".config" contents are compressed and saved in the U-Boot image, then printed by the new command "config". The usage is quite simple. Enable CONFIG_CMD_CONFIG, then run > config from the command line interface. The ".config" contents will be printed on the console. This feature increases the U-Boot image size by about 4KB (this is mostly due to the gzip-compressed .config file). By default, it is enabled only for Sandbox because we do not care about the memory footprint on it. Of course, this feature is architecture agnostic, so you can enable it on any board if the image size increase is acceptable for you.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
