Bootm: remove uimage_close done later in bootm_boot ...

Subject: [PATCH] Bootm: fix double uimage_close

When uimage crc fails, the error handling path call uimage_close in
bootm_open_os_uimage and also in bootm_boot. This leads to crash/exception.
Keep the main error handling path in bootm_boot and remove uimage_close from
bootm_open_os_uimage to avoid double uimage_close.

ARM: dts: bcm2835-rpi: re-enable booting from SD card ...

Kernel commit a19adf8 [0] changed the
RPi1 device tree from &sdhci to &sdhost, which was imported in barebox
commit d14b844. It seems that barebox
does not have a driver for brcm,bcm2835-sdhost (yet), which resulted in
barebox unable to boot from SD card. However, the driver for
brcm,bcm2835-sdhci worked fine in the past.

Although the upstream change was made for good reasons, the simplest
change for barebox for now is to revert to using &sdhci and disable
&sdhost.

Thanks to Alexander Dahl for raising this issue on the DistroKit
mailing list!

There are many places where sphinx complains that blocks cannot

style to shell which fits our needs much better. With this we
get rid of many warnings while building the documentation.

fs: Fix can_lseek_backward() ...

To quote corresponding man page:

"... Upon successful completion, lseek() returns the resulting offset
location as measured in bytes from the beginning of the file."

Which for lseek(fd, 0, SEEK_SET) would be 0, so returning 'ret' as
final step of the function would mean it'd never return anything but 0
as well. Change the code to explicitly return '1' to fix the problem.

uimage: fix: add can_lseek_backward and use in uimage_open ...

Since commit ce0cc7fe we support forward seek on tftpfs. This feature
breaks the condition to check rather we open an uimage over tftp. Since
backward seeking is the problem here, we add the function
can_lseek_backward and check for it instead of the simple lseek.
