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.

ARM: sunxi: Add basic A23 support The basic blocks of the A23 are similar to the A31 (sun6i). Re-use sun6i code for initial clock, gpio, and uart setup. There is no SPL support for A23, as we do not have any documentation or sample code for DRAM initialization.

sun8i: Add dram initialization support Based on the register / dram_para headers from the Allwinner u-boot / linux sources + the init sequences from boot0. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk> 2014-12-07 13:34:27 +00:00
sunxi: A23/A33/H3: Actually move the secure monitor commit 1ebfc0c631e3 ("sunxi: A23/A33/H3: Move sun8i secure monitor to SRAM A2") attempted to move the secure monitor to SRAM A2. But not all sun8i SoCs have SRAM A2, so a check was put in for SUNXI_SRAM_A2_SIZE to avoid breaking the other SoCs. However, because the header providing SUNXI_SRAM_A2_SIZE was not included, this unintentionally skipped the new definitions on all SoCs. Fix this by including the right header.

sunxi: A23/A33/H3: Move sun8i secure monitor to SRAM A2 So far for the H3, A23, and A33 SoCs, we use DRAM to hold the secure monitor code (providing PSCI runtime services). And while those SoCs do not have the secure SRAM B like older SoCs, there is enough (secure) SRAM A2 to put the monitor code and data in there instead. Follow the design of 64-bit SoCs and use the first part for the monitor, and the last 16 KiB for the SCP firmware. With this change, the monitor no longer needs to reserve a region in DRAM.
