relocation. Also provide symbols for the relocation
code to access the table.
Discard all sections which are not needed in the final
ELF binary and U-Boot image. Section .dynsym cannot be
discarded or GNU ld crashes otherwise. This section
will be stripped by GNU objcpy in a later patch.

Use the newly introduced symbol __image_copy_end as end address for
relocation of U-Boot image. This is needed for dynamic relocation added
in later patches. This patch obsoletes the symbols uboot_end and

Get the start and end address for clearing BSS from the newly
introduced symbols __bss_start and __bss_end. After GOT is
relocated, those symbols are already pointing to the correct
addresses.
Also optimize the loop by moving the address incrementation
to the delay slot to avoid the initial sub instruction.

The execution order of the bootm subcommands is fixed.
Although here is a sanity check in the state machine
which should prevent running the subcommands in wrong
order but it does not catch all possible errors.
It is possible to run any subcommand without running
'bootm start' first which leads to unexpected behaviour.
For example, running 'bootm loados' without 'bootm start'
causes a hang:
U-Boot> bootm loados
XIP Invalid Image ... OK
OK
Add a sanity check to 'do_bootm_subcommand' in order
to ensure that no subcommands can be executed before
'bootm start'.
After the patch running of any subcommand without running
'bootm start' will cause an error like this:
U-Boot> bootm loados
Trying to execute a command out of order

Currently we have "unsigned long blkcnt" which is fine with
CONFIG_SYS_64BIT_LBA undefined because "lbaint_t" is basically the same
"unsigned long".
If CONFIG_SYS_64BIT_LBA gets defined "lbaint_t" is defined as "unsigned
long long".
Even though not many embedded systems have CONFIG_SYS_64BIT_LBA defined
it's good to have types in function implementation that match exactly
with prototypes.

ifdefs in the code are making it harder to read.
The use of simple if(vfat_enabled) makes no more code and is cleaner.
(the code is discarded by the compiler instead of the preprocessor.)
NB: if -O0 is used, the code won't be discarded
and bonus, now the code compiles even if CONFIG_SUPPORT_VFAT is not
defined.
