cmd: mmc: check whether card is SD or eMMC before hwpartition

2021-10-29T09:22:32+00:00

It doesn't need to follow more sequence to do the hwparititioning, because SD doesn't support hwpartitioning feature. Signed-off-by: Jaehoon Chung Reviewed-by: Peng Fan Signed-off-by: Jaehoon Chung

cmd: mmc: Support mmc hwpartition user enh start -

2021-10-29T09:22:32+00:00

Add option to extend the hardware partition to the maximum size by using the '-' dash sign instead of $cnt parameter. This is useful in case we want to switch the entire eMMC user area into pSLC mode, especially in case the device may be populated with different size eMMCs. With this change, we do not have to calculate the number of blocks of the user area manually. To switch the pSLC mode for user area, use e.g. the following. WARNING: This is a one-time irreversible change. => mmc hwpartition user enh 0 - wrrel on complete Signed-off-by: Marek Vasut Cc: Fabio Estevam Cc: Jaehoon Chung Cc: Peng Fan Cc: Stefano Babic Signed-off-by: Jaehoon Chung

mmc: Add support for enumerating MMC card in a given mode using mmc command

2021-09-10T10:17:04+00:00

Add support for enumerating MMC card in a given mode using mmc rescan and mmc dev commands. The speed mode is provided as the last argument in these commands and is indicated using the index from enum bus_mode in include/mmc.h. A speed mode can be set only if it has already been enabled in the device tree. Signed-off-by: Aswath Govindraju Reviewed-by: Jaehoon Chung Tested-by: Jaehoon Chung

global: Convert simple_strtoul() with decimal to dectoul()

2021-08-02T17:32:14+00:00

It is a pain to have to specify the value 10 in each call. Add a new dectoul() function and update the code to use it. Signed-off-by: Simon Glass

global: Convert simple_strtoul() with hex to hextoul()

It is a pain to have to specify the value 16 in each call. Add a new hextoul() function and update the code to use it. Add a proper comment to simple_strtoul() while we are here. Signed-off-by: Simon Glass

mmc: Update environment variable with active partition

2021-06-22T04:02:46+00:00

This patch allows uboot scripts make choices about where to boot from based on the active mmc boot partition. This allows having two copies of kernel, filesystems etc, and choosing which to boot from based off of the active bootloader partition. Signed-off-by: Reuben Dowle Reviewed-by: Jaehoon Chung

According to Specification, each bit have valid value. But it doesn't check whether arguments is valid or not. It has potential bug with arguments passed by wrong value. Signed-off-by: Jaehoon Chung

cmd: mmc: modify more readable about hwpartition usage

2021-04-06T10:08:14+00:00

Modified more readable about hwpartition usage. Because it's difficult to understand how to use its command. The arguments didn't optional. mmc hwpartition needs to pass as arguments. Description about each arguments what is required is the below: USER - <{on|off}> GP - <{gp1|gp2|gp3|gp4}> <{on|off}> MODE - <{check|set|complete}> Signed-off-by: Jaehoon Chung
