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] Signed-off-by: Evgeniy Didin <didin@synopsys.com> Cc: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Cc: Alexey Brodkin <abrodkin@synopsys.com> Cc: arc-buildroot@synopsys.com Reviewed-by: Romain Naour <romain.naour@smile.fr> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
