RTEMS 14-03-14 tests on CSB336 - SPI SD-card correction etc.

[Pavel Pisa]

Hello Sebastian and others,

I have found time to test RTEMS GIT on LPC1788
in last days and it works OK. I have tried to
run code on CSB336/MXS based platform and I have
noticed two problems.

The firs is broken filesystem embedding at least
on my setup. The embedded untar breaks if directory
already exists. And default tar includes './'
in archive. Next change/workaround solves the problem

          if ( mkdir(fname, S_IRWXU | S_IRWXG | S_IRWXO) != 0 ) {
+           if (!strcmp(fname, "/") || !strcmp(fname, "./"))

            printk("Untar: failed to create directory %s\n", fname);
            retval = UNTAR_FAIL;
            break;

But I think that it should not be solved this way.
I expect that  use of stat() libc function to check for directory
existence before mkdir attempt is better. If you agree with
this solution, I can prepare patch.

I have tested SD-card support on git RTEMS version as well.
There is one obvious problem introduced when core block devices
API has been changed. I am sending patch for this problem as followup.
But there seems to be some yet another problem on our HW even
after this correction. The fix helps that a partition is correctly
recognized but write has some problems. But that is for some
other drop of available time and can be really only problem of our
HW.

Best wishes,
