From mboxrd@z Thu Jan 1 00:00:00 1970 From: Evgeniy Didin Date: Tue, 19 Dec 2017 17:55:54 +0300 Subject: [Buildroot] [PATCH v2] board: add support for ARC HS Development Kit (HSDK) Message-ID: <20171219145554.17718-1-didin@synopsys.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net 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.
