2020-05-18command: Remove the cmd_tbl_t typedefSimon Glass
We should not use typedefs in U-Boot. They cannot be used as forward declarations which means that header files must include the full header to access them. Drop the typedef and rename the struct to remove the _s suffix which is now not useful. This requires quite a few header-file additions. Signed-off-by: Simon Glass <sjg@chromium.org>

2020-05-10cmd: nandbcb: Reconstruct the nandbcb tool for all platformsHan Xu
The original nandbcb tool was designed for imx6 only, when trying to leverage it to replace the kobs-ng tool, we found the design is not friendly for supporting all platforms. To support all iMX6/7/8 platforms and for easy further maintain, I reconstruct the structure of the tool. The main changes including: 1. Use platform_data to determine the logic branches rather than simply use SOC name. 2. More data structures as parameter for functions. 3. Global variables to define the FCB/DBBT/FW locations. 4. Implement the kobs-ng default 4 FCB/4 DBBT/2 FW layout. 5. Support Hamming coding/ 40bit BCH/ 62bit BCH coding FCB. 6. Dump and compare all written FCB/DBBT to verify data integrity. The tool has been verified on iMX6Q/DL, 6SX, 7D, 6ULL, iMX8QX, iMX8MM. Signed-off-by: Han Xu <han.xu@nxp.com> Signed-off-by: Peng Fan <peng.fan@nxp.com>

2020-02-05dm: core: Create a new header file for 'compat' featuresSimon Glass
At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-02-05dm: core: Require users of devres to include the headerSimon Glass
At present devres.h is included in all files that include dm.h but few make use of it. Also this pulls in linux/compat which adds several more headers. Drop the automatic inclusion and require files to include devres themselves. This provides a good indication of which files use devres.

2019-12-04cmd: nand/sf: isolate legacy codeMiquel Raynal
The 'sf' command is not supposed to rely on the MTD stack, but both 'sf' and 'nand' commands use helpers located in mtd_uboot.c. Despite their location, these functions do not depend at all on the MTD stack. This file (drivers/mtd/mtd_uboot.c) is only compiled if CONFIG_MTD is selected, which is inconsistent with the current situation. Solve this by moving these three functions (which are only used by the above two commands) out of mtd_uboot.c and put them in a C file only compiled with cmd/sf.c and cmd/nand.c.

2019-07-19i.MX6: nand: add nandbcb command for imxShyam Saini
Writing/updating boot image in nand device is not straight forward in i.MX6 platform and it requires boot control block(BCB) to be configured. It becomes difficult to use uboot 'nand' command to write BCB since it requires platform specific attributes need to be taken care of. It is even difficult to use existing msx-nand.c driver by incorporating BCB attributes like mxs_dma_desc does because it requires change in mtd and nand command. So, cmd_nandbcb implemented in arch/arm/mach-imx BCB contains two data structures, Firmware Configuration Block(FCB) and Discovered Bad Block Table(DBBT). FCB has nand timings, DBBT search area, page address of firmware. On summary, nandbcb update will - erase the entire partition - create BCB by creating 2 FCB/DBBT block followed by 1 FW block based on partition size and erasesize. - fill FCB/DBBT structures - write FW/SPL on FW1 - write FCB/DBBT in first 2 blocks for nand boot, up on reset bootrom look for FCB structure in first block's if FCB found the nand timings are loaded for further reads. once FCB read done, DTTB will load and finally firmware will be loaded which is boot image. Refer section "NAND Boot" from doc/imx/common/imx6.txt for more usage information.
