/* 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.
