* ath79: lzma-loader: allow setting custom kernel magicMichael Pratt2021-04-081-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | ...and max flash offset The mtdsplit parser was recently refactored to allow the kernel to have custom image header magic. Let's also do this for the lzma-loader For example: When implemented together, this allows the kernel to "appear" to be a rootfs by OEM software in order to write an image that is actually kernel + rootfs. At the same time, it would boot to openwrt normally by setting the same magic in DTS. Both of the variables have a default value that is unchanged when not defined in the makefiles This has no effect on the size of the loader when lzma compressed.

* ath79: move lzma-loader to the end of available RAMAdrian Schmutzler2020-01-231-2/+2
| | | | | | | | | | | | | | | | | | | | | In certain cases, the uncompressed initramfs image will overwrite the lzma-loader, which is currently only 10 MB away from kernel image start. To prevent this, change LZMA_TEXT_START to 24 MB, so loader and compressed image have 8 MB at the end of RAM and uncompressed image has 24 MB available. This is only enabled for ath79 at the moment, as there we can be sure that all devices have 32+ MB RAM and TARGET_INITRAMFS_COMPRESSION_LZMA is not enabled there. Despite, since lzma-loader is currently build specifically for ath79 anyway, there is no need to re-specify LOADADDR and LZMA_TEXT_START in image/Makefile, so the values are set directly in image/lzma-loader/Makefile and the overwrite in image/Makefile is removed.

* ath79: lzma-loader: sync with ar71xx targetMatthias Schiffer2018-06-061-1/+5
| | | | | | | | | | | | | | Import all improvements made in the lzma-loader since development on the ath79 target started. This also reverts fe594bf90d09 ("ath79: fix loader-okli, lzma-loader"), as is obsoleted by 2ad60168b6af ("ar71xx: lzma-loader: move padding workaround to gzip step"). Likely, many of the changes should be ported to the ramips lzma-loader as well, but I don't have a device to test this. Signed-off-by: Matthias Schiffer <mschiffer@universe-factory.net>
* ath79: add new OF only target for QCA MIPS siliconJohn Crispin2018-05-071-0/+66
This target aims to replace ar71xx mid-term. The big part that is still missing is making the MMIO/AHB wifi work using OF. NAND and mikrotik subtargets will follow. Signed-off-by: John Crispin <john@phrozen.org>
