usb_storage: fix ehci driver max transfer size

2012-07-18T12:46:19+00:00

The commit 5dd95cf93dfffa1d19a1928990852aac9f55b9d9 'usb_storage:
Fix EHCI "out of buffer pointers" with CD-ROM' introduce a bug in
usb_storage as it wrongly assumes that every transfer can use
4096 bytes per qt_buffer. This is wrong if the start address of
the data is not page aligned to 4096 bytes and leads to 'EHCI
timed out on TD' messages because of 'out of buffer pointers'
in ehci_td_buffer function.

The bug appears during load of a fragmented file and
read from or write to an unaligned memory address.

USB: Align buffers at cacheline

2012-05-20T06:32:32+00:00

This avoids cache-alignment warnings shown in console
when a usb command is entered.

Whenever X bytes of unaligned buffer is invalidated, arm core
invalidates X + Y bytes as per the cache line size and throws
these warnings.

usb: replace wait_ms() with mdelay()

2012-03-18T23:08:16+00:00

Common code has a mdelay() func, so use that instead of the usb-specific
wait_ms() func.  This also fixes the build errors:

usb_storage: Fix EHCI "out of buffer pointers" with CD-ROM

2012-01-05T19:10:38+00:00

When performing large bulk reads from a CD or DVD using the U-Boot
usb_storage driver, it generates requests of up to 20 blocks at a time.

With a standard 512-byte block size, that is 10240 bytes and within the
limit of U-Boot's EHCI driver (maximum 5 pages at 4k per page).

Unfortunately CD-ROM media has a 2048-byte blocksize, resulting in a
maximum transfer size of 40960 bytes, which does not fit.

Since the EHCI specification is impossibly obtuse and far beyond my
comprehension, I chose to dynamically compute the limit based on the
blocksize.

Revert "GCC4.6: Convert various empty macros to inline functions"

2011-10-04T19:19:19+00:00

This reverts commit 60ce53cf9f408d9ad721f8e7a87d6a564e6d5bac.

The commit causes build breakage for a number of boards. This results
from the fact that now the arguments of debug() actually get
referenced (even if there is hope that the compiler will optimize
away the debug() call).  The obvious fix to that probem (change the
code to always declare the referenced variables and data structures)
increases the code size, and was this rejected.  So it was decided to
revert this commit until a better solution is found.

If we don't want to build support for any partition types we can now
add #undef CONFIG_PARTITIONS in a board config file to keep this from
being compiled in. Otherwise boards assume this is compiled in by
default
