gd->bd->bi_baudrate is a copy of gd->baudrate.
Since baudrate is a common feature for all architectures,
keep gd->baudrate only.
It is true that bi_baudrate was passed to the kernel in that structure
but it was a long time ago.

With d6a320d we moved some clock externs out of blackfin_local.h and
into clock.h but now need to include <asm/clock.h> in more drivers to
avoid warnings.

Current code uses gd->baudrate before setting its value.
Besides, I got below build warning which is introduced by
commit ddb5c5be "blackfin: add baudrate to bdinfo".
board.c:235:3: warning: passing argument 1 of 'simple_strtoul' makes pointer from integer without a cast [enabled by default]
include/vsprintf.h:27:7: note: expected 'const char *' but argument is of type 'unsigned int'
This patch ensures we get the baudrate setting before using it.

This field gets read in one place (by "bdinfo"), and we can replace
that with getenv("ipaddr"). After all, the bi_ip_addr field is kept
up-to-date implicitly with the value of the ipaddr env var.

We don't need these setup manually, so let the bss do the rest. On
Blackfin systems, we clear the bss before executing any C code that
would use these, so this should be fine.

This patch removes the architecture specific implementation of
version_string where possible. Some architectures use a special place
and therefore we provide U_BOOT_VERSION_STRING definition and a common
weak symbol version_string.

The recent global data changes (making the size autogenerated) broke the
board info handling on Blackfin ports as we were lying and lumping the
bd_t size in with the gd_t size. So use the new dedicated bd_t size to

CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not
being able to use "sizeof(struct global_data)" in assembler files.
Recent experience has shown that manual synchronization is not
reliable enough. This patch renames CONFIG_SYS_GBL_DATA_SIZE into
GENERATED_GBL_DATA_SIZE which gets automatically generated by the
asm-offsets tool. In the result, all definitions of this value can be
deleted from the board config files. We have to make sure that all
files that reference such data include the new <asm-offsets.h> file.
No other changes have been done yet, but it is obvious that similar
changes / simplifications can be done for other, related macro
definitions as well.

The CONFIG_BFIN_CPU option is largely used in the build system, so move
it out of the board config.h and into the board config.mk. It'd be nice
to keep everything in the config.h, but the patch to extract that value
early was rejected.

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"]
