| | | | | | | | | | | | | | The Netgear WN2500RP V1 switch0 already works for LAN however the port order for the LAN ports is inverted.

* brcm47xx: rework model detectionJo-Philipp Wich2018-07-302-18/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | On brcm47xx boards, the model ID is the combination of the "boardtype" nvram variable and an optional supplemental "boardnum" variable while the human readable model name is usually exposed in the "machine" field of the /proc/cpuinfo file. Move the extraction of the board nvram variables and model name string into the 01_sysinfo file and rework the 01_detect board configuration script to solely use the prepared sysinfo values without performing own detection logic. As a consequence, we can drop the ucidef_set_board_id() and ucidef_set_model_name() invocations in favor to the generic behaviour which copies the /tmp/sysinfo/{board_name,model} values into the board.json "id" and "name" fields respectively. Since "01_detect" only contains network configuration logic after this change, move it to "01_network" and rename the contained "detect_by_xxx" functions to "configure_by_xxx" instead, to avoid potential confusion.

* brcm47xx: switch to the kernel 4.14Rafał Miłecki2018-05-081-1/+1
| | | | | | | | | | | | | | | | | | The biggest (and the only?) disadventage of this is obviously an increased image size. For mips74k the size of vmlinux goes up from 4186684 B to 4701436 B. Most devices use LZMA compressed kernel so probably more important is vmlinux.lzma size which goes up from 1342945 B to the 1508498 B. Still this isn't something that should stop target kernel bump. There are various adventages of kernel 4.14. If kernel / image size is a serious concern for anyone, it's perfectly possible to use previous release which is pretty solid for the brcm47xx.

* brcm47xx: fix switch port mapping on Asus RT-N16Tim Thorpe2017-11-101-1/+1
| | | | | | | On the Asus RT-N16, the ports are not mapped the in the same way as the RT-N12. It is, however, the same as the Linksys E3000v1. Signed-off-by: Tim Thorpe <timfthorpe@gmail.com>
* brcm47xx: use kernel 4.9 by defaultHauke Mehrtens2017-10-181-1/+1
| | | | | | | | Kernel 4.9 is now working on the brcm47xx boards, we just recently fixed the problem that some boards did not boot at all, by changing the memory regions used to relocate the kernel to in the loader. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
* brcm47xx: relocate the stack in loaderHauke Mehrtens2017-10-112-2/+4
| | | | | | | | | | | By default we are reusing the stack provided by CFE, like it is intended by CFE. On my WRT54GS it is located at 0x8043BF30, so a big kernel image could overwrite it. Relocate it to a different memory region which is still under the 8MB RAM, but in the higher area. We only need this memory region for the stack of the loader, Linux will set up this for its own.

* brcm47xx: relocate loader to higher addressHauke Mehrtens2017-10-111-1/+1
| | | | | | | | | | | | | | | | | | | | | The boot process on a WRT54GL works the following way: 1. CFE gets loaded by the boot rom from flash 2. CFE loads the loader from the flash and gzip uncompresses it 3. CFE starts the loader 4. The loader stores the FW arguments and relocates itself to BZ_TEXT_START (now 0x80600000) 5. The loader reads the Linux image from flash 6. The loader lzma decompresses the Linux image to LOADADDR (0x80001000) 7. The loader executes the uncompress Linux image at LOADADDR The BZ_TEXT_START was set to 0x80400000 before. When the kernel gets uncompressed and is bigger than BZ_TEXT_START - LOADADDR it overwrote the loader which was currently uncompressing it and made the board crash. Increase the BZ_TEXT_START my 2 MB to have more space for the kernel. Even on 16MB RAM devices the memory goes till 0x80FFFFFF so this should not be a problem.
