[U-Boot] [PATCH V8 0/9] EXYNOS5: Enable DWMMC, add FDT support for DWMMC and
by Amar 23 Apr '13

23 Apr '13

This patch set enables and initialises DWMMC for Exynos5250 on SMDK5250. Adds driver changes required for DWMMC. Adds FDT support for DWMMC. Adds EMMC boot support for SMDK5250. This patch set is based on: "EXYNOS: mmc: support DesignWare Controller for Samsung-SoC", which is merged in u-boot-mmc. "Exynos: clock: support get_mmc_clk for exynos". "Add DT based ethernet driver for SMDK5250". "SMDK5250: Add FDT support" present at the following link http://comments.gmane.org/gmane.comp.boot-loaders.u-boot/149991 Changes since V1: 1)Corrected in response to review comments. 2)Created separate board files for FDT and non-FDT versions. 3)Added binding file for DWMMC device node. 4)Removed the propname 'index' from device node. 5)Prefixed the vendor name 'samsung' before propname in device node. 6)Ensured to have same signature for the function exynos_dwmci_init() for both FDT and non-FDT versions. 7)EMMC clock setting has been moved from spl_boot.c to clock_init.c. Changes since V2: 1)Updation of commit message and resubmition of proper patch set. Changes since V3: 1)Updated to use the macro DWMCI_CTRL_SEND_AS_CCSD instead of the hard coded value (1 << 10). 2)In the file exynos_dw_mmc.c, replaced the new function exynos5_mmc_set_clk_div() with the existing function set_mmc_clk(). set_mmc_clk() will do the purpose. 3)In the file exynos_dw_mmc.c, computation of FSYS block clock divisor (pre-ratio) value is added. 4)Removed the new function exynos5_mmc_set_clk_div() from clock.c. Changes since V4: 1)Updated the function dwmci_send_cmd() to use get_timer() instead of using mdelay(1). 2)Replaced the function call 'exynos_dwmmc_init(0, 8);' with the function exynos_dwmmc_add_port() in smdk5250.c. 3)The function get_irom_func(int index) has been added to avoid type casting at many places. 4)Used the generic function "mmc_boot_part_access()" instead of two functions "mmc_boot_open()" and "mmc_boot_close()". By doing so user can specify which boot partition to be accessed (opened / closed). Changes since V5: 1)Added the 'removable' flag to mmc device node. 2)Changed the mmc clock value from 50MHz to 52MHz in the function exynos_dwmci_add_port() present in file drivers/mmc/exynos_dw_mmc.c. 3)Enabled CONFIG_LCD only for non-FDT operation. 4)Removed the function call i2c_init() present inside the function board_i2c_init(). Changes since V6: 1)Re-based to the patch "SMDK5250: Add PMIC voltage settings". Changes since V7: 1)Re-based to the patch "Exynos: pwm: Remove dead code of function exynos5_get_pwm_clk". 2)In file dw_mmc.c, updated the function dwmci_setup_bus() to return 0 if (freq == 0).This is to avoid the run time exception "raise:Signal # 8 caught". 3)In the files drivers/mmc/mmc.c and common/cmd_mmc.c, the piece of code involved in EMMC open/close and resize of EMMC boot partition has been made conditional and is enabled only if the macro CONFIG_SUPPORT_EMMC_BOOT is defined. 4)The macros FSYS1_MMC0_DIV_MASK and FSYS1_MMC0_DIV_VAL are made local to file clock_init.c.

[U-Boot] Driver Model Thoughts
by Simon Glass 22 Apr '13

22 Apr '13

Hi Marek, Another U-Boot engineer and I are looking at running up driver model. It seems to work in sandbox quite nicely. I had half a mind to try to get some core patches together for this merge window, but have questions. For 'struct instance' it seems to be an attempt to keep the constant data separate from the dynamic data to reduce early RAM usage. But when I look at struct driver_instance, it seems to have a 'struct instance' within it (not a pointer). So doesn't this defeat that benefit? You presumably can't put struct driver_instance in read-only memory because you need it updates its flags. I still have trouble keeping track of some of the naming - e.g. and instance feels to me like it should be called a device, and the naming of 'core' seems odd although I do understand the concept. Also bind/unbind seems like register/unregister to me - but maybe there is a difference. There is: struct driver_info struct instance struct core_instance struct driver_instance struct u_boot_driver struct u_boot_core Anyway I'll leave that alone for now. There seems to be a lot of boilerplate code about. For example the bind/unbind methods just call a core_...() function and it seems that the core library could do this itself. It seems to me that some of the methods could be NULL for most drivers, and that would reduce the porting effort. If we do this I would like to build in device tree from the start so that on boards that use CONFIG_OF_CONTROL there is no need for static data. I think the existing 'demo' driver is a really good idea since it gives people something to copy. Regards, Simon

[U-Boot] [PATCH v3 0/19] Allow images to work on sandbox
by Simon Glass 22 Apr '13

22 Apr '13

This series adjusts the image code to work with sandbox and prepares it for verified boot to come later. The primary goal here is to get image loading to work on sandbox, which is mostly a set of fairly minor changes such as using map_sysmem() instead of just a cast when converting from a U-Boot address to a pointer. Since common/image.c runs to over 3000 lines and half of it is FIT-related code behind an #ifdef, this code is moved into a new image-fit.c file. This series depends on the sandbox generic board series: sandbox: Generic board support and other improvements Changes in v3: - Update notes to note that generic board support has now landed - Split out image improvements into a separate series Changes in v2: - Change hash_block() to use an unsigned int len - Clarify use of output_size parameter to hash_block() - Fix line continuation problem - Fix checkpatch checks about parenthesis alignment - Rebase on previous patches - Rebase on previous patches - Rebase on previous patches - Add IMAGE_ENABLE_IGNORE to avoid #ifdef around ignore property handling - Rename commit message to say "function" instead of "function" - Rebase on previous patches - Put err_msgp strings on a single line - Rebase on previous patches - Put params before description in fit_conf_get_prop_node() comment - Rebase on previous patches - Rebase on previous patches - Fix checkpatch checks about parenthesis alignment Simon Glass (19): env: Fix minor comment typos in cmd_nvedit Add minor updates to README.fdt-control hash: Add a way to calculate a hash for any algortihm bootstage: Don't build for HOSTCC mkimage: Move ARRAY_SIZE to header file libfdt: Add fdt_next_subnode() to permit easy subnode iteration image: Move timestamp #ifdefs to header file image: Export fit_check_ramdisk() image: Split FIT code into new image-fit.c image: Move HOSTCC image code to tools/ image: Split hash node processing into its own function image: Convert fit_image_hash_set_value() to static, and rename image: Rename fit_image_check_hashes() to fit_image_verify() image: Move hash checking into its own function image: Move error! string to common place image: Export fit_conf_get_prop_node() image: Rename fit_add_hashes() to fit_add_verification_data() image: Rename hash printing to fit_image_print_verification_data() sandbox: image: Add support for booting images in sandbox common/Makefile | 1 + common/cmd_bootm.c | 25 +- common/cmd_fpga.c | 2 +- common/cmd_nvedit.c | 4 +- common/cmd_source.c | 2 +- common/cmd_ximg.c | 2 +- common/hash.c | 23 + common/image-fit.c | 1497 ++++++++++++++++++++++++++++++++++++++++++ common/image.c | 1679 ++---------------------------------------------- common/update.c | 2 +- doc/README.fdt-control | 9 +- include/bootstage.h | 5 +- include/hash.h | 22 + include/image.h | 55 +- include/libfdt.h | 17 + lib/libfdt/fdt.c | 12 + tools/Makefile | 4 + tools/aisimage.c | 1 - tools/fit_image.c | 2 +- tools/image-host.c | 213 ++++++ tools/mkimage.h | 2 + 21 files changed, 1903 insertions(+), 1676 deletions(-) create mode 100644 common/image-fit.c create mode 100644 tools/image-host.c -- 1.8.2.1
