The gdsys gazerbeam board is based on a Freescale MPC8308 SOC.
It boots from NOR-Flash, kernel and rootfs are stored on
SD-Card.
On board peripherals include:
- 2x 10/100 Mbit/s Ethernet (optional)

To support OF_EMBED, the MPC83xx architecture has to define the "_end"
symbol to correctly access the appended DT.
Fortunately, MPC8xx already defines the symbol, and the linker script is
quite similar to that of MPC83xx, so copy this approach for MPC83xx.

For a lot of inline assembly calls in the mpc8xxx and mpc83xx
directories, we already have convenient pre-defined helper functions,
but they're not used, resulting in hard-to-read code.
Use these helper functions where ever possible and useful.

ppcDWstore/ppcDWload are hardly used by any board, but since they're
implemented in start.S, they're always present in every U-Boot image,
even if they're not needed.
Re-implement these fuctions in C with inline assembly, so that the
compiler can decide when to actually include them.

Migrate the BR/OR settings to Kconfig. These must be known at compile
time, so cannot be configured via DT.
Configuration of this crucial variable should still be somewhat
comfortable. Hence, make its fields configurable in Kconfig, and

The MPC83xx DM timer driver disables arch.pciexp*_clk, and uses
clk_get_rate instead. But the legacy MPC83xx PCIe driver still uses

driver.

MPC83xx uses CONFIG_83XX_CLKIN instead of CONFIG_SYS_CLK_FREQ to set the
system clock. To migrate the architecture, we can replace
CONFIG_83XX_CLKIN with CONFIG_SYS_CLK_FREQ.
To do this
* replace all occurrences of CONFIG_83XX_CLKIN with CONFIG_SYS_CLK_FREQ
* set CONFIG_SYS_CLK_FREQ to the old value of CONFIG_83XX_CLKIN in all
MPC83xx config files

CONFIG_SYS_CLK_FREQ is the standard way to set the system clock
frequency. On MPC83xx, CONFIG_83XX_CLKIN is used for this purpose.
Hence, the obvious way is to replace CONFIG_83XX_CLKIN with
CONFIG_SYS_CLK_FREQ.
A few MPC83xx boards use the CONFIG_83XX_CLKIN variable for computing
CONFIG_SYS_NS16550_CLK. This makes it harder to replace
CONFIG_83XX_CLKIN.
But the value of the multiplicator can be read from the SPMR register.
Hence, replace the static calculations with a call to a new get_bus_freq
function, as other architectures do.

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.

At present we support multiple environment drivers but there is not way to
select between them at run time. Also settings related to the position and
size of the environment area are global (i.e. apply to all locations).
Until these limitations are removed we cannot really support more than one
environment location. Adjust the location to be a choice so that only one
can be selected. By default the environment is 'nowhere', meaning that the
environment exists only in memory and cannot be saved.
Also expand the help for the 'nowhere' option and move it to the top since
it is the default.
