The rest of the unmigrated CONFIG symbols in the CONFIG_SYS_SDRAM

be available to host tools but we do know the size that we passed to

- On some platforms that were using the standard calculation but did not
  set CONFIG_SYS_INIT_RAM_SIZE / CONFIG_SYS_INIT_RAM_ADDR, set them.
- On a small number of platforms that were not subtracting
  GENERATED_GBL_DATA_SIZE do so now via the standard calculation.

b2e373d16b rockchip: allow loading larger kernels
Recent versions of the Linux kernel with many options enabled have
grown large enough to overwrite the beginning of the initrd. For
example, the kernel I use on my Rock64 and RockPro64 is 34.1 MiB,
while only 31.5 MiB are available between kernel_addr_r and
ramdisk_addr_r.

This patch moves ramdisk_addr_r up by 32 MiB on the RK3328 and RK3399,
allowing for much larger kernels.

limit the SPL size in 0x40000(start from 0) so that we don't need to do

Note that there will be separate BSS, STACK and MALLOC heap, so the size
0x40000(256KB) should be enough for SPL text.

2acc24fc28 Kconfig: Migrate BOUNCE_BUFFER
The bounce buffer is used by a few drivers (most of the MMC drivers)
to overcome limitations in their respective DMA implementation.

This moves the configuration to Kconfig and makes it user-selectable
(even though it will be a required feature to make those drivers
work): the expected usage is for drivers depending on this to 'select'
it unconditionally from their respective Kconfig (see follow-up
patches).

This commit includes a full migration using moveconfig.py to ensure
that each commit compiles.  To ensure bisectability we update
dependencies of various drivers to now select BOUNCE_BUFFER when needed.

83d290c56f 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.

0c8e0b319f rockchip: add text_offset to kernel_addr_r on aarch64 platforms
Booting a aarch64 Linux kernel requires the image to be placed
text_offset bytes from a 2MB aligned address.
See https://www.kernel.org/doc/Documentation/arm64/booting.txt

booti_setup() takes care about this alignment and will relocate the
image if not properly aligned with memmove(). This can require up
to double the size of the loaded image and therefore accidentally
overwrite content placed there (i.e ramdisk_addr_r) for large kernel
images.

By adding text_offset to the default kernel_addr_r we can prevent that
from happening for kernels larger 18MB and also save a few cycles.

We can assume a text_offset of 0x80000 for most cases, all others will be
handled by booti_setup() anyway.
