The S25FS-S family physical sectors may be configured as a hybrid
combination of eight 4-kB parameter sectors at the top or bottom
of the address space with all but one of the remaining sectors
being uniform size.
The default status of the flash is in this hybrid architecture.
The parameter sectors and the uniform sectors have different erase
commands.
This patch disable the hybrid sector architecture then the flash will
has uniform sector size and uniform erase command.
This configuration is temporary, the flash will revert to hybrid
architecture after power on reset.

get_timer() returns an unsigned 64-bit value, but is currently assigned to
a signed 32-bit variable. Due to sign extension and data truncation, this
causes the timeout loop in spi_flash_cmd_wait_ready() to immediately (and
incorrectly) fire for about 50% of all time values, based on whether bit
31 is set. In sandbox at least, this causes the test to pass or fail based
on system uptime, as opposed to time since the U-Boot binary was started.

The stm_is_locked_sr() function is picked from Linux kernel. For reason
unknown, the 64bit data types used by the function and present in Linux
were replaced with 32bit unsigned ones, which causes trouble.
The testcase performed was done using ST M25P80 chip.
The command used was:
=> sf protect unlock 0 0x10000
The call chain starts in stm_unlock(), which calls stm_is_locked_sr()
with negative ofs argument. This works fine in Linux, where the "ofs"
is loff_t, which is signed long long, while this fails in U-Boot, where
"ofs" is u32 (unsigned int). Because of this signedness problem, the
expression past the return statement to be incorrectly evaluated to 1,
which in turn propagates back to stm_unlock() and results in -EINVAL.
The correction is very simple, just use the correctly sized data types
with correct signedness in the function to make it work as intended.

Make spl_*_load_image() functions return a value instead of

to make the decision whether to hang or not, thus preparing
it to support alternative boot devices.
Some boot devices (namely nand and spi) do not hang on error.
Instead, they return normally and SPL proceeds to boot the
contents of the load address. This is considered a bug and
is rectified by hanging on error for these devices as well.
