Right now the u-boot,dm-pre-reloc flag will make each marked node always appear in both spl and tpl. But systems needing an additional tpl might have special constraints for each, like the spl needing to be very tiny.

So introduce two additional flags to mark nodes for only spl or tpl environments and introduce a function dm_fdt_pre_reloc to automate the necessary checks in code instances checking for pre-relocation flags.

The behaviour of the original flag stays untouched and still marks a node for both spl and tpl.

The gpll and cpll init values are only used in rk_clk_init in the SPL and therefore produce compile time warnings in regular uboot builds. Fix that with an #ifdef.

Add the core architecture code for the rk3188. It doesn't support the SPL yet, as because of some unknown error it doesn't start yet.

The sdram controller blocks are very similar to the rk3288 in utilizing memory scheduler, Designware uPCTL and Designware PUBL blocks, only limited to one bank instead of two.

There are some minimal differences when setting up the ram, so it gets a separate driver for the rk3188 but reuses the driver structs, as there is no need to define the same again.

More optimization can happen when the modelling of the controller parts in the dts actually follow the hardware layout hopefully at some point in the future.

The Rock is a RK3188 based single board computer by Radxa. Currently it still relies on the proprietary DDR init and cannot use the generic SPL, but at least is able to boot a linux kernel and system up to a regular login prompt.

Building sd images for rk3188 requires more steps due to the needed split into TPL and SPL as loaders. Describe how to build an image for it in a separate paragraph in the READER.rockchip file.

+ +Booting from an SD card on RK3188 +================================= + +For rk3188 boards the general storage onto the card stays the same as +described above, but the image creation needs a bit more care. + +The bootrom of rk3188 expects to find a small 1kb loader which returns +control to the bootrom, after which it will load the real loader, which +can then be up to 29kb in size and does the regular ddr init. + +Additionally the rk3188 requires everything the bootrom loads to be +rc4-encrypted.
