env: Rename environment.h to env_internal.h

2019-08-11T23:27:31Z

This file contains lots of internal details about the environment. Most code can include env.h instead, calling the functions there as needed. Rename this file and add a comment at the top to indicate its internal nature.

env: Drop environment.h header file where not needed

nand: davinci: add support for driver model

2019-07-29T21:58:52Z

Extend the davinci NAND driver to support the driver model. For now this doesn't add any device-tree parsing due to the fact that we can't access the actual nand node on the device-tree - it's a subnode of the aemif device and we don't have an aemif driver on davinci at the moment.

i.MX6: nand: add nandbcb command for imx

2019-07-19T12:51:25Z

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. Reviewed-by: Stefano Babic Signed-off-by: Jagan Teki Signed-off-by: Sergey Kubushyn Signed-off-by: Shyam Saini

mtd: spi: Add flash property for Micron mt25qu512a

2019-07-18T11:41:16Z

mt25qu512a is rebranded after its spinoff from STM, so it is different only in term of extended jedec ID, initial JEDEC id is same as that of n25q512a.In order to avoid any confussion with respect to name new entry is added. This flash is tested for Single I/O mode on LS1046FRWY although it also support QUAD I/O. Signed-off-by: Ashish Kumar Reviewed-by: Jagan Teki
