* mpc85xx: add support for cpu type 8548 8540 cpu type corresponds to e500v1 core while 8548 cpu type corresponds to e500v2 core See https://www.nxp.com/products/processors-and-microcontrollers/legacy-mpu-mcus/powerquicc-processors:POWERQUICC_HOME#powerquicc-iii-mpc85xx and https://www.nxp.com/docs/en/application-note/AN2807.pdf . Co-authored-by: Josef Schlehofer <josef.schlehofer@nic.cz> Co-authored-by: Pali Rohár <pali@kernel.org> Signed-off-by: Šimon Bořek <simon.borek@nic.cz> * tree-wide: Do not use package librt and libpthread The libraries libpthread, libdl, libutil, libanl have been integrated into the libc library in version 2.34. it is not needed to explicitly link them any more. Most of the functions have been moved from the librt.so into libc.so some time ago already. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> * toolchain/binutils: backport stable patches Add the patches with real changes from the binutils 2.39 stable branch. I am not aware that we ran into any of these problems, but I think it is better to take the existing stable patches. They were exported like this: git format-patch binutils-2_39...origin/binutils-2_39-branch I removed the patches changing the version numbers only. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> * toolchain/binutils: switch to version 2.39 by default This was build tested with all core packages on all targets successfully. This was run tested on the following systems: * lantiq/xrx200 musl * sunxi/cortex53 musl * x86/64 musl * x86/64 glibc Some trusted firmware arm builds needed some fixes to build with binutils 2.39, this was merged before. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> * tools: Improve diffability/maintainability There's no purpose to squish multiple tools into a single line (and spread those out over multiple lines). It might look 'nice' in certain conditions, but it's annoying to maintain. For example, but not limited to: * adding/removing tools, causes hard to read diffs * Duplicates are harder to spot * Sorting can not be (easily?) automated With this proposed change, the above annoyances go away. Inserting a new tool can be done with a single line-change-diff, sorting can be done by any editor (in vi, select, :sort for example) and dupes are much easier to spot. Signed-off-by: Olliver Schinagl <oliver@schinagl.nl> * rules: drop -Wno-error additional flags from default TARGET_CFLAGS We currently enable -Wno-error=unused-but-set-variable and -Wno-error=unused-result by default on every compile package. While this is (relatively) unharmful, we should follow other project direction and starts enforcing good code quality. For example the linux kernel recently started to enforce Wall by default and clean code is mandatory for inclusion. Drop for good these flags and and make it mandatory to correctly handle return values at least with a warning log if they are not strictly error condition. Signed-off-by: Christian Marangi <ansuelsmth@gmail.com> * bridger: update to the latest version def7755c459d add missing copyright headers f68307fd96d7 add hairpin mode support 9ee8f433ba4e nl: do not pass NDA_VLAN with vid=0 978c1f9eed07 add support for the bridge port isolated flag Signed-off-by: Felix Fietkau <nbd@nbd.name> Signed-off-by: Šimon Bořek <simon.borek@nic.cz> Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: Olliver Schinagl <oliver@schinagl.nl> Signed-off-by: Christian Marangi <ansuelsmth@gmail.com> Signed-off-by: Felix Fietkau <nbd@nbd.name> Co-authored-by: Šimon Bořek <simon.borek@nic.cz> Co-authored-by: Josef Schlehofer <josef.schlehofer@nic.cz> Co-authored-by: Pali Rohár <pali@kernel.org> Co-authored-by: Hauke Mehrtens <hauke@hauke-m.de> Co-authored-by: Olliver Schinagl <oliver@schinagl.nl> Co-authored-by: Christian Marangi <ansuelsmth@gmail.com> Co-authored-by: Felix Fietkau <nbd@nbd.name>
