Storing LFS erase size in the boot byte is not possible
because Linux kernel is unable to detect the partitions
after change boot bytes to values other than 0x80 or 0x00
In this patch LFS_BLOCK_SIZE is moved to the second
MBR bootcode AREA
Functions were refactored and renamed for better readability.
Some of them were moved to different files. In stat_vfs function
the order of member initializations was corrected.
VFAT partition should be mounted in RO mode by default
because writing to FAT filesystem is unsafe.
Writing is allowed only in the LFS filesystem.
If upgrade is needed FAT partition can be temporary
switched to RW mode using mount() syscall with REMOUNT flag
but it should be switched to RO mode again after upgrade.
MMC erase group size is 512 kB which would enforce
512 kB blocks on file system. Since for our purposes this
would be inefficient erase command has been disallowed.
Disk access was not protected by the mutex and race contition
occurs when multiple access was made for lfs and fat.

Script for generate partitions for emulator by mistake
overwrites the littlefs image and fatfs image due to the
overlap fat parition and littlefs partition

This is a first commit when the emulator uses
the new filesystem core.

IOSYSCALS_REDIRECT_TO_IMAGE
When IOSYSCALS_REDIRECT_TO_IMAGE=1 all syscalls
are redirected to the image. If env is not defined
or set to 0 only paths are translated and redirected
to the native linux syscalls

Default automount and parse partitions according to
their configurations using new vfs core. Currently
old (without lfs) and new (with lfs) part schemes are supported
Opening file with O_CREAT mode on the mounted fat filesystem
should create file if doesn't exist. Currently it returns ENOENT
This path fix this issue. ff_fat create flags are fixed.
