packages/boot: remove rbcfg

2020-05-28T09:09:10Z

The new sysfs soft_config driver makes buggy rbcfg obsolete and entirely replaces it. Signed-off-by: Thibaut VARÈNE

generic: routerboot sysfs: soft_config support for ath79 cpufreq

2020-05-28T09:09:10Z

This commit introduces support for R/W access to the CPU frequency setting of routerboot on ath79 hardware. On unsupported hardware, the sysfs attribute will expose the raw tag value (read-only) to help with reverse engineering its meaning.

generic: routerboot sysfs: add support for soft_config

2020-05-28T09:09:10Z

This driver exposes the data encoded in the "soft_config" flash segment of MikroTik RouterBOARDs devices. It presents the data in a sysfs folder named "soft_config" through a set of human-and-machine-parseable attributes. Changes can be discarded by writing 0 to the 'commit' attribute, or they can be committed to flash storage by writing 1. This driver does not reuse any of the existing code previously found in the "rbcfg" utility and makes this utility obsolete by providing a clean sysfs interface. Like "rbcfg", this driver requires 4K_SECTORS support since the flash partition in which these parameters are stored is typically 4KB in size.

This routine will be shared between hard and soft config drivers. Also use scnprintf() instead of snprintf(). Tested-by: Koen Vandeputte Tested-by: Roger Pueyo Centelles Signed-off-by: Thibaut VARÈNE

generic: platform/mikrotik: rb_hardconfig.c minor fixes

2020-05-28T09:09:10Z

For the sake of strictly typed code, add a missing const qualifier. Add a missing return value in error path. Check the return value of mtd_read(), for good measure. Also demote the error printks of failed sysfs file creation to warn level since they are not fatal in the init() sequence. Finally, add a note regarding PAGE_SIZE and clarify a comment.
