The RK3399-Q7 is a system-on-module featuring the Rockchip RK3399 in a Qseven-compatible form-factor.
These changes add a device-tree describing the board and its interfaces for basic functionality (e.g. GbE, SPI, eMMC, SD-card).
This includes the following changes from the original development:
* dts: rk3399-puma: include DTS for RK3399-Q7 SoM in the Makefile * dts: rk3399-puma: add gmac for the RK3399-Q7
This change enables the Gigabit Ethernet support on the RK3399-Q7.
* dts: rk3399-puma: use serial0 for stdout * dts: rk3399-puma: prepare the sdmmc node for SPL booting * dts: rk3399-puma: enable spi1 and spi5, add /spi1/spiflash
The RK3399-Q7 (Puma) unsually (this is a build-time option for customised boards) has an on-module SPI-flash connected to SPI1. As of today, this is a Winbond W25Q32DW (32MBit) device.
The SPI5 controller is routed to the Q7 edge connector and provides general-purpose SPI connectivity for customer base-boards.
With some minor improvements on integration into our outbound tree - explicitly modelled the SPI flash as 'spiflash' under spi0 [dts: rk3399-puma: explicitly model spi-flash under spi1] - renamed the aliases to spi0 and spi1 to allow easier use of commands and legacy (SPL) infrastructure... i.e. the controllers will be 0 and 1 for 'sf probe', 'sspi', etc. [dts: rk3399-puma: rename aliases to number spi as 0 and 1 for commands]
* dts: rk3399-puma: include SPI in the spl-boot-order property
