swig has been installed on the buildbots a while a ago and Petr Štetiar got a fix for the pylibfdt error. Use that and re-enable the builds for mt7620 and mt7621. Refresh patches while at it. Signed-off-by: Daniel Golle <daniel@makrotopia.org>

Subject: [PATCH 07/25] doc: mediatek: add documentation for mt7621 reference
|
|
boards
|
|
|
|
The MT7621 requires external binary blob being executed during u-boot's
|
|
boot-up flow. It's necessary to provide a guide here for users to correctly
|
|
build the u-boot.

+==========================
|
|
+
|
|
+U-Boot for the MediaTek MT7621 boards
|
|
+
|
|
+Quick Start
|
|
+-----------
|
|
+
|
|
+- Get the DDR initialization binary blob
|
|
+- Configure CPU and DDR parameters
|
|
+- Build U-Boot
|
|
+
|
|
+Get the DDR initialization binary blob
|
|
+--------------------------------------
|
|
+
|
|
+Download one from:
|
|
+ - https://raw.githubusercontent.com/mtk-openwrt/mt7621-lowlevel-preloader/master/mt7621_stage_sram.bin
|
|
+ - https://raw.githubusercontent.com/mtk-openwrt/mt7621-lowlevel-preloader/master/mt7621_stage_sram_noprint.bin
|
|
+
|
|
+mt7621_stage_sram_noprint.bin has removed all output logs. To use this one,
|
|
+download and rename it to mt7621_stage_sram.bin
|
|
+
|
|
+Put the binary blob to the u-boot build directory.
|
|
+
|
|
+Configure CPU and DDR parameters
|
|
+--------------------------------
|
|
+
|
|
+menuconfig > MIPS architecture > MediaTek MIPS platforms > CPU & DDR configuration
|
|
+
|
|
+Select the correct DDR timing parameters for your board. The size shown here
|
|
+must match the DDR size of you board.
|
|
+
|
|
+The frequency of CPU and DDR can also be adjusted.
|
|
+
|
|
+Build U-Boot
|
|
+------------
|
|
+
|
|
+.. code-block:: bash
|
|
+
|
|
+ $ export CROSS_COMPILE=mipsel-linux-
|
|
+ $ make O=build mt7621_rfb_defconfig # or mt7621_nand_rfb_defconfig
|
|
+ $ cp mt7621_stage_sram.bin ./build/mt7621_stage_sram.bin
|
|
+ $ # or cp mt7621_stage_sram_noprint.bin ./build/mt7621_stage_sram.bin
|
|
+ $ make O=build
|
|
+
|
|
+Burn the u-boot-mt7621.bin to the SPI-NOR or NAND flash.
