This is for the RFS file system. There is a bug in the
rtems_rfs_bitmap_create_search loop. It is supposed to iterate
over the range of bits in a search element ( usually 32 bits ),
so it should loop through bits 0 through 31. Instead it loops
through 0 - 32, causing some blocks not to be allocated. As in
PR 2163, this depends on the block size and number of blocks in
a file system. Block sizes and group sizes that are powers of 2
seem to work fine ( 512 byte blocks, 4096 block groups, etc ).
When the block sizes are not powers of 2, then this loop error
causes some of the blocks at the end of a group to be skipped,
preventing 100% of the blocks from being used. A simple test
for this and PR2163 is to create a RAM disk with block size
3900 and at least 1 full group ( 31200 blocks ). A file system
with these sizes will not be able to allocate 100% of the blocks.
This is for the RFS file system. The statvfs call reports 1 block free
when the file system is full because it does not account for the superblock
in its calculation of free blocks.
This is a simple fix that adjusts the number of blocks reported to account
for the superblock. We may want to wait for a more complete solution such
as locating the superblock in each group.
This is for the RFS file system. There is a bug in the group search
algorithm where it will skip groups, causing blocks to remain
unallocated. This is dependant on the size of the blocks and number
of blocks in a group, so it does not always show up. The fix corrects
the skipping of groups during the search, allowing all of the blocks
to be found.
Control the help command break with the SHELL_LINES evironment variable
where the numeric value is the number of lines to break on. If the
value is 0 the output is not broken. The default is 16 lines.
Add shell documentation for the help command.
The function-like macro ERC32_Is_interrupt_masked defined as:
(ERC32_MEC.Interrupt_Masked & (1 << (_source)))
The ERC32_MEC is of type ERC32_Register_Map structure and Interrupt_Masked does
not exist in structure, instead Interrupt_Mask exists.
Update the macro accordingly.
This test formerly had a bug in that it attempted to wait on a
condition variable with a Mutex that was not locked. This is
undefined by POSIX. But a recent change to match GNU/Linux behavior
resulted in finding a bug in the test.

Provide a weak call to a clock freq routine to allow the application
to supply the freq defined in the Xilinx generated source.
Add code to calculate the baud rate.
This error check was commented out because it is not in the POSIX
specification. However, the GNU/Linux manual page does document
that EPERM is to be returned in this situation.
