From: Christian Lamparter Date: Thu, 5 May 2022 16:16:25 +0000 (+0200) Subject: apm821xx: add support for kernel 5.15 for testing X-Git-Tag: v23.05.0-rc1~3457 X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b2c9c4dda28dd9bd82df629d96d626d2c236f382;p=openwrt%2Fstaging%2Fpepe2k.git apm821xx: add support for kernel 5.15 for testing This patch copies over refreshed config and patches from 5.10 with the following changes: - dropped superfluous tc654/tc655 variant detection patch (tc654 support will become available upstream starting with 5.17-rc7+). - dropped xhci msi(x) workaround... as the broken MSI(X) is now gone. - dropped dwc2 workaround since the driver was fixed and it works without it. Please note: Netgear WNDAP660 & WNDAP620 users: Due to the kernel's size increase, uboot will likely break because it is overwrite the kernel during decompression. To fix this (and debrick affected devices, no reflash necessary), attach the RJ45-Serial-Console cable and enter the following in the uboot prompt during bootup: setenv kernel_addr_r 1100000 saveenv run bootcmd to restore the old/previous behavior: setenv kernel_addr_r 600000 saveenv run bootcmd Signed-off-by: Christian Lamparter --- diff --git a/target/linux/apm821xx/Makefile
