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.

This allows us to use the same DRAM init function on all archs. Add a
dummy function for arc, which does not use DRAM init here.

At present we cannot use this function as an init sequence call without a
wrapper, since it returns the RAM size. Adjust it to set the RAM size in
global_data instead, and return 0 on success.

It looks like only cm5200 and tqm8xx use this feature, so we don't really
need it in generic code. Drop it and have the users access gd->board_type
directly.

This patch cleans up the Freescale MPC8308RDB Development board support.
Things fixed:
- Removed unused PCIE2 definitions from configuration
- SICR{L,H} defines used for System I/O Configuration Registers values
instead of hardcoding
- CONFIG_SYS_SCCR_PCIEXP1CM used to enable PCIE clock instead of
writing to SCCR from the board code
- sleep mode stuff removed as MPC8308 has no support for deep sleep and
PMCCR1 register. board_early_init_f() removed.
- MPC8308 has no ERRATA for DDR controller so workaround removed
- 'assignment in if statement' issues solved
- use LBLAWAR_* defines instead of hardcoding

This patch provides support for MPC8308RDB development board from
Freescale with a minimal set of features:
Dual UART is supported
NOR flash is supported
Both TSEC Ethernet controllers are supported
PCI Express initialization is supported
The following features are enabled in configuration but not fully tested:
I2C (used to get the board revision)
I2C-connected RTC
VSC7385 switch
There is one (hopefully) minor issue: on soft reset the board sometimes
resets twice. I've not managed to find the fix for this problem yet.
As a workaround instruction cache can be disabled.
