menu: fix timeout duration
For distro-boot, the TIMEOUT directive in the boot script specifies
how long to pause in units of 1/10 sec. [1]
Commit 8594753ba0a7 ("menu: only timeout when menu is displayed")
corrected this by simply dividing the timeout value by 10 in
menu_interactive_choice().
I see two problems:
- For example, "TIMEOUT 5" should wait for 0.5 sec, but the current
implementation cannot handle the granularity of 1/10 sec.
In fact, it never breaks because "m->timeout / 10" is zero,
which means no timeout.
- The menu API is used not only by cmd/pxe.c but also by
common/autoboot.c . For the latter case, the unit of the
timeout value is _second_ because its default is associated
with CONFIG_BOOTDELAY.
To fix the first issue, use DIV_ROUND_UP() so that the timeout value
is rounded up to the closest integer.
For the second issue, move the division to the boundary between
cmd/pxe.c and common/menu.c . This is a more desirable place because
the comment of struct pxe_menu says:
* timeout - time in tenths of a second to wait for a user key-press before
* booting the default label.
Then, the comment of menu_create() says:
* timeout - A delay in seconds to wait for user input. If 0, timeout is
* disabled, and the default choice will be returned unless prompt is 1.

disk: efi: Correct backing up the MBR boot code
In commit e163a931af34 ("cmd: gpt: backup boot code before writing MBR")
there was added the procedure for storing old boot code when doing "gpt
write". But instead of storing just backup code, the whole MBR was
stored, and only specific fields were replaced further, keeping
everything else intact. That's obviously not what we want.
Fix the code to actually store only old boot code and zero out
everything else. This fixes next testing case:
In case when $loadaddr address and further memory contains 0xff, the
board was bricked (ROM-code probably didn't like partition entries that
were clobbered with 0xff). With this patch applied, commands above don't
brick the board.

sf: Set current flash bank to 0 in clean_bar()
The clean_bar() function resets the SPI NOR BAR register to 0, but
does not set the flash->curr_bar to 0 , therefore those two can get
out of sync, which could ultimatelly result in corrupted flash content.
The simplest test case is this:
=> mw 0x10000000 0x1234abcd 0x4000
=> sf probe
=> sf erase 0x1000000 0x10000
=> sf write 0x10000000 0x1000000 0x10000
=> sf probe ; sf read 0x12000000 0 0x10000 ; md 0x12000000
That is, erase a sector above the 16 MiB boundary and write it with
random pre-configured data. What will actually happen without this
patch is the sector will be erased, but the data will be written to
BAR 0 offset 0x0 in the flash.
This is because the erase command will call write_bar()+clean_bar(),
which will leave flash->bank_curr = 1 while the hardware BAR registers
will be set to 0 through clean_bar(). The subsequent write will also
trigger write_bar()+clean_bar(), but write_bar checks if the target
bank == flash->bank_curr and if so, does NOT reconfigure the BAR in
the SPI NOR. Since flash->bank_curr is still 1 and out of sync with
the HW, the condition matches, BAR programming is skipped and write
ends up at address 0x0, thus corrupting flash content.
