-/* 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.

- * RTC test
- *
- * The Real Time Clock (RTC) operation is verified by this test.
- * The following features are verified:
- *   o) RTC Power Fault
- *	This is verified by analyzing the rtc_get() return status.
- *   o) Time uniformity
- *      This is verified by reading RTC in polling within
- *      a short period of time.
- *   o) Passing month boundaries
- *      This is checked by setting RTC to a second before
- *      a month boundary and reading it after its passing the
- *      boundary. The test is performed for both leap- and
- *      nonleap-years.
