branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
Synopsys DesignWare HSDK (which stands for ARC HS
Development Kit) is the latest and greatest development
platform that sports quad-core ARC HS38 in real silicon.
Most noticeable features of the board are:
* Quad-core ARC HS38 CPU running at 1GHz
* 4Gb of DDR
* Built-in Vivante GPU (well supported via open source
Etnaviv drivers)
* Built-in Wi-Fi/Bluetooth module (RedPine RS-9113)
And as usual we have:
* [micro] SD-card slot
* 2 USB 2.0 ports
* 1Gbit Ethernet port
* Built-in Digilent JTAG probe
* Serial port accessible via micro-USB port
Writing sdcard.img on SDcard creates two partitions:
* FAT32 with uImage and uboot.env
* EXT4 with root filesystem
We modify kernel config because in default hsdk kernel config
CONFIG_INITRAMFS_SOURCE parameter is set and when we build
rootfs separately (BR2_TARGET_ROOTFS_INITRAMFS is not set)
error appears. Also we set up CONFIG_ARC_UBOOT_SUPPORT which
enables usage of uboot variables in the boot process.
[Peter: Fix comments and rename defconfig to snps_archs38_hsdk_defconfig,
Add defconfig to DEVELOPERS and fixup board/synopsys entry,
Drop postimage script, rename env file in genimage.cfg and drop size
setting for rootfs partition,
Add "" for CONFIG_INITRAMFS_SOURCE in linux fragment]
