rockchip: sdram: add basic support for sdram reg info version 3 Newer DRAM initialization blobs from vendor can encode sdram info in a new version 3 format. The new format makes use of more bits in sys_reg3 compared to the version 2 format. Add basic support for detecting the version 3 format and decoding the high bits used for ddrtype. This fixes decode of sdram size on my RK3568 boards that have LPDDR4X. Details on the new format was deciphered from vendor u-boot commit [1].

rockchip: sdram: extend to use sys_reg3 for capacity info Since we have new DRAM type and to support different DRAM size in different CS, we need more bits, so introduce sys_reg3 to record the info. Note that the info in sys_reg3 is extension to sys_reg2 and the info in sys_reg2 is the same as before. We define the DRAM_INFO with sys_reg3 as VERSION2. All the ENC macro are moved to sdram_common.h since the sdram.c only need to do the info decode.

SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com> |
