* kernel: support for RTL8367C/S switchMieczyslaw Nalewaj2024-02-24
| | | | | | | | | | | | | | | | | | | From driver point of view no differance between rtl8367b and rtl8367s if it connected through EXT2 (rgmii only). So this trivial patch add some identification and initialization only. SGMII/HSGMII mode for EXT1 is not implemented for the sake of patch clairity.

* kernel: rtl8366_smi: explicitly set phy addr for switchMieczyslaw Nalewaj2024-02-24

* kernel: move uImage.FIT partition parser to mediatek targetDaniel Golle2024-02-15
| | | | | | | | | | The partition parser approach has been rejected upstream, it will be replaced by a small block driver which is the solution suggestion by upstream maintainers. As the partition parser has only been used by the mediatek target, as a first step, move it there. Signed-off-by: Daniel Golle <daniel@makrotopia.org>

* generic: rtl8366_smi: rename and drop conflicting vlan GPL symbolsChristian Marangi2023-10-06
| | | | | | | | | | | | Symbol rtl8366_enable_vlan and rtl8366_reset_vlan are also present in the DSA driver upstream and conflicts as they are EXPORTED. Rename them to rtl8366_smi_enable_vlan and rtl8366_smi_reset_vlan to fix the conflict. While at it also make them static and drop the EXPORT_SYMBOL_GPL as they are not actually used by any other driver and exporting them is useless.

The mtk_bmt driver recursively calls its scan_bmt() helper function during device initialization, while looking for a valid block mapping table (BMT). 2. Commit fa4dc86e98 ("kernel: backport MEMREAD ioctl"): - increased the size of some stack-allocated structures (like struct mtd_oob_ops, used in bbt_nand_read(), which is indirectly called from scan_bmt()), - increased the stack size for some functions (for example, spinand_mtd_read(), which is indirectly called from scan_bmt(), now uses an extra stack-allocated struct mtd_ecc_stats). 3. OpenWrt currently compiles the kernel with the -fno-optimize-sibling-calls flag, which prevents tail-call optimization. Collectively, all of these factors caused stack usage in the mtk_bmt driver to grow excessively large, triggering stack overflows. Recursion is not really necessary in scan_bmt() as it simply iterates over flash memory blocks in reverse order, looking for a valid BMT. Refactor the logic contained in the scan_bmt() and read_bmt() functions in target/linux/generic/files/drivers/mtd/nand/mtk_bmt_v2.c so that deep recursion is prevented (and therefore also any potential stack overflows it may cause).

* kernel: mtdsplit: add support for H3C VFS filesystemJan Hoffmann2022-07-28
| | | | | | | | | | | | | | | | The bootloader on some H3C devices (for example HPE 1920 switches) only supports booting from flash by reading an image from an "VFS" filesystem which spans most of the available flash. The filesystem size is hard- coded in the bootloader. However, as long as no write operations are performed in the bootloader menu, it is sufficient if the start of the partition contains a valid filesystem with the kernel image. This mtdsplit parser reads the size and location of the kernel image and finds the location of the rootfs stored after it. It assumes that the filesystem image matches the layout of one generated by mkh3cvfs, with a filename of "openwrt-kernel.bin" for the kernel image. Signed-off-by: Jan Hoffmann <jan@3e8.eu>
