Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""

2024-05-19T14:16:36Z

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master. This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35. Reported-by: Jonas Karlman Signed-off-by: Tom Rini

cmd: Convert existing long help messages to the new macro

2023-10-16T14:24:58Z

- Generally we just drop the #ifdef CONFIG_SYS_LONGHELP and endif lines and use U_BOOT_LONGHELP to declare the same variable name as before - In a few places, either rename the variable to follow convention or introduce the variable as it was being done inline before.

i2c: Remove CONFIG_I2C_MULTI_BUS

2022-12-22T15:31:48Z

This functionality is part of the legacy I2C subsystem and is currently unused anywhere. Remove the remaining references. Signed-off-by: Tom Rini

global: Move remaining CONFIG_SYS_* to CFG_SYS_*

2022-12-05T21:06:08Z

The rest of the unmigrated CONFIG symbols in the CONFIG_SYS namespace do not easily transition to Kconfig. In many cases they likely should come from the device tree instead. Move these out of CONFIG namespace and in to CFG namespace. Signed-off-by: Tom Rini Reviewed-by: Simon Glass

i2c: fix stack buffer overflow vulnerability in i2c md command

2022-08-31T16:21:47Z

This reinstates fix from commit 8f8c04bf1ebb ("i2c: fix stack buffer overflow vulnerability in i2c md command") without the changes unrelated to the actual fix. Avoid the underflow by setting only nbytes and linebytes as unsigned integers. Signed-off-by: Marek Vasut Cc: Heiko Schocher Cc: Nicolas Iooss Cc: Simon Glass Cc: Tim Harvey Acked-by: Tim Harvey

This reverts commit 8f8c04bf1ebbd2f72f1643e7ad9617dafa6e5409. The commit is largely wrong and breaks most of i2c command functionality. The problem described in the aforementioned commit commit message is valid, however the commit itself does many more changes unrelated to fixing that one problem it describes. Those extra changes, namely the handling of i2c device address length as unsigned instead of signed integer, breaks the expectation that address length may be negative value. The negative value is used by DM to indicate that address length of device does not change. The actual bug documented in commit 8f8c04bf1ebbd2f72f1643e7ad9617dafa6e5409 can be fixed by extra sanitization in separate patch.
