This function consists entirely of inline asm statements, so writing
it directly in a .S file is simpler. Additionally, the inline asm is
not safe as is, since registers are not guaranteed to be preserved
between asm() statements.

On OMAP34xx ES1.0, the L2 enable bit can only be set in secure mode,
so an SMC call to the ROM monitor is required. On later versions,
and on newer devices, this bit is banked and we can set it directly.
The code checked only the ES revision of the chip, and hence incorrectly
used the ROM call on ES1.0 versions of other devices.
This patch adds a check for chip family as well as revision, and also
removes some code duplication between the enable and disable functions.

This patch fixes a bug in reconfigure_pll(), where the detection of
the current bootstrap option is wrong. The ICS bits where incorrectly
shifted. This bug was found on the lwmon5 board, which uses bootstrap
option H (I2C bootstrap EEPROM).
Additionally a bit of code was moved into the if statement, since its
only used after later on. No need to run this code all the time.
Also, a few empty lines are added to make the code better readable.

There is a limitation (or bug?) of nios2 toolchain. The nios2 gcc
didn't generate correct code when the reset vector is passed as a
constant. It just generated a direct "call", which was wrong when
the reset vector was not located in the same 256MB span as u-boot.
The "Nios II Processor Reference Handbook" said,
"call can transfer execution anywhere within the 256 MByte range
determined by PC31..28. The Nios II GNU linker does not automatically
handle cases in which the address is out of this range."
So we have to use registered "callr" instruction to do the job.

In case there is no frame buffer driver present in Linux to hand over the
PPI LCD DMA upon boot, the DMA initiated by u-boot to display the splash
screen runs unattended. Therefore always stop the video driver in u-boot
before starting Linux. If people don't want this behavior, then they can
simply stub out the video_stop() function in their board video driver.

Platforms with flat device tree support can use a bootmap to relocate
the fdt_blob. This is not a must. That's why the relocation function
boot_relocate_fdt() should be use only if CONFIG_OF_LIBFDT was defined
together with CONFIG_SYS_BOOTMAPSZ (see common/cmd_bootm.c).
On MicroBlaze platforms there is no need to use a bootmap to relocate
a fdt blob. So we need a more precise focus on the compilation and usage
of boot_relocate_fdt().
In general it is valid to exclude the function boot_relocate_fdt() if
the bootmap size CONFIG_SYS_BOOTMAPSZ is not defined.

While running from flash, i. e. before relocation, we have only a
limited C runtime environment without writable data segment. In this
phase, some configurations (for example with environment in EEPROM)
must not use the normal getenv(), but a special function. This
function had been called getenv_r(), with the idea that the "_r"
suffix would mean the same as in the _r_eentrant versions of some of
the C library functions (for example getdate vs. getdate_r, getgrent
vs. getgrent_r, etc.).
Unfortunately this was a misleading name, as in U-Boot the "_r"
generally means "running from RAM", i. e. _after_ relocation.
To avoid confusion, rename into getenv_f() [as "running from flash"]
