-The TRAB keyboard implementation is similar to that for LWMON and
-R360MPI boards. The only difference concerns key naming. There are 4
-keys on TRAB: 1, 2, 3, 4.
-
-1) The "kbd" command provides information about the current state of
- the keys. For example,
-
- TRAB # kbd
- Keys: 1 0 1 0
-
- means that keys 1 and 3 are pressed. The keyboard status is also
- stored in the "keybd" environment variable. In this example we get
-
- keybd=1010
-
-2) The "preboot" variable is set according to current environment
- settings and keys pressed. This is an example:
-
- TRAB # setenv magic_keys XY
- TRAB # setenv key_magicX 12
- TRAB # setenv key_cmdX echo ## Keys 1 + 2 pressed ##\;echo
- TRAB # setenv key_magicY 13
- TRAB # setenv key_cmdY echo ## Keys 1 + 3 pressed ##\;echo
-
- Here "magic_keys=XY" means that the "key_magicX" and "key_magicY"
- variables will be checked for a match. Each variable "key_magic*"
- defines a set of keys. In the our example, if keys 1 and 3 are
- pressed during reset, then "key_magicY" matches, so the "preboot"
- variable will be set to the contents of "key_cmdY":
-
- preboot=echo ## Keys 1 + 3 pressed ##;echo
-
-3) The TRAB board has optional modem support. When a certain key
- combination is pressed on the keyboard at power-on, the firmware
- performs the necessary initialization of the modem and allows for
- dial-in. The key combination is specified in the
- "include/configs/trab.h" file. For example:
-
- #define CONFIG_MODEM_KEY_MAGIC "23"
-
- means that modem will be initialized if and only if both keys 2, 3
- are pressed. Note that the format of this string is similar to the
- format of "key_magic*" environment variables described above.

-/* 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)
