ARM: drop unsupported 'trab' board

The 'trab' board configuration is broken, and there is nobody who is
interested and willing to fix it.  Drop it.

This includes support for VFD displays which have always been used by
this board only.

-/* Memory test
- *
- * General observations:
- * o The recommended test sequence is to test the data lines: if they are
- *   broken, nothing else will work properly.  Then test the address
- *   lines.  Finally, test the cells in the memory now that the test
- *   program knows that the address and data lines work properly.
- *   This sequence also helps isolate and identify what is faulty.
- *
- * o For the address line test, it is a good idea to use the base
- *   address of the lowest memory location, which causes a '1' bit to
- *   walk through a field of zeros on the address lines and the highest
- *   memory location, which causes a '0' bit to walk through a field of
- *   '1's on the address line.
- *
- * o Floating buses can fool memory tests if the test routine writes
- *   a value and then reads it back immediately.  The problem is, the
- *   write will charge the residual capacitance on the data bus so the
- *   bus retains its state briefely.  When the test program reads the
- *   value back immediately, the capacitance of the bus can allow it
- *   to read back what was written, even though the memory circuitry
- *   is broken.  To avoid this, the test program should write a test
- *   pattern to the target location, write a different pattern elsewhere
- *   to charge the residual capacitance in a differnt manner, then read
- *   the target location back.
- *
- * o Always read the target location EXACTLY ONCE and save it in a local
- *   variable.  The problem with reading the target location more than
- *   once is that the second and subsequent reads may work properly,
- *   resulting in a failed test that tells the poor technician that
- *   "Memory error at 00000000, wrote aaaaaaaa, read aaaaaaaa" which
- *   doesn't help him one bit and causes puzzled phone calls.  Been there,
- *   done that.
- *
- * Data line test:
- * ---------------
- * This tests data lines for shorts and opens by forcing adjacent data
- * to opposite states. Because the data lines could be routed in an
- * arbitrary manner the must ensure test patterns ensure that every case
- * is tested. By using the following series of binary patterns every
- * combination of adjacent bits is test regardless of routing.
- *
- *     ...101010101010101010101010
- *     ...110011001100110011001100
- *     ...111100001111000011110000
- *     ...111111110000000011111111
- *
- * Carrying this out, gives us six hex patterns as follows:
- *
- *     0xaaaaaaaaaaaaaaaa
- *     0xcccccccccccccccc
- *     0xf0f0f0f0f0f0f0f0
- *     0xff00ff00ff00ff00
- *     0xffff0000ffff0000
- *     0xffffffff00000000
- *
- * To test for short and opens to other signals on our boards, we
- * simply test with the 1's complemnt of the paterns as well, resulting
- * in twelve patterns total.
- *
- * After writing a test pattern. a special pattern 0x0123456789ABCDEF is
- * written to a different address in case the data lines are floating.
- * Thus, if a byte lane fails, you will see part of the special
- * pattern in that byte lane when the test runs.  For example, if the
- * xx__xxxxxxxxxxxx byte line fails, you will see aa23aaaaaaaaaaaa
- * (for the 'a' test pattern).
- *
- * Address line test:
- * ------------------
- *  This function performs a test to verify that all the address lines
- *  hooked up to the RAM work properly.  If there is an address line
- *  fault, it usually shows up as two different locations in the address
- *  map (related by the faulty address line) mapping to one physical
- *  memory storage location.  The artifact that shows up is writing to
- *  the first location "changes" the second location.
- *
- * To test all address lines, we start with the given base address and
- * xor the address with a '1' bit to flip one address line.  For each
- * test, we shift the '1' bit left to test the next address line.
- *
- * In the actual code, we start with address sizeof(ulong) since our
- * test pattern we use is a ulong and thus, if we tried to test lower
- * order address bits, it wouldn't work because our pattern would
- * overwrite itself.
- *
- * Example for a 4 bit address space with the base at 0000:
- *   0000 <- base
- *   0001 <- test 1
- *   0010 <- test 2
- *   0100 <- test 3
- *   1000 <- test 4
- * Example for a 4 bit address space with the base at 0010:
- *   0010 <- base
- *   0011 <- test 1
- *   0000 <- (below the base address, skipped)
- *   0110 <- test 2
- *   1010 <- test 3
- *
- * The test locations are successively tested to make sure that they are
- * not "mirrored" onto the base address due to a faulty address line.
- * Note that the base and each test location are related by one address
- * line flipped.  Note that the base address need not be all zeros.
- *
- * Memory tests 1-4:
- * -----------------
- * These tests verify RAM using sequential writes and reads
- * to/from RAM. There are several test cases that use different patterns to
- * verify RAM. Each test case fills a region of RAM with one pattern and
- * then reads the region back and compares its contents with the pattern.
- * The following patterns are used:
- *
- *  1a) zero pattern (0x00000000)
- *  1b) negative pattern (0xffffffff)
- *  1c) checkerboard pattern (0x55555555)
- *  1d) checkerboard pattern (0xaaaaaaaa)
- *  2)  bit-flip pattern ((1 << (offset % 32))
- *  3)  address pattern (offset)
- *  4)  address pattern (~offset)
- *
- * Being run in normal mode, the test verifies only small 4Kb
- * regions of RAM around each 1Mb boundary. For example, for 64Mb
- * RAM the following areas are verified: 0x00000000-0x00000800,
- * 0x000ff800-0x00100800, 0x001ff800-0x00200800, ..., 0x03fff800-
- * 0x04000000. If the test is run in slow-test mode, it verifies
- * the whole RAM.
