created and tested cmd_encod_tiled_32_wr.v - tiles with 32-byte columns

 * up to 1 kB. Memory is mapped so 8 consecuitive rows have same RA, CA

 * and alternating BA (0 to 7). Data will be read in columns 32 bytes wide,

 * then proceding to the next column (if >1).

 * This is a modification of Module: cmd_encod_tiled_32_rd module,

 * This is a modification of module: cmd_encod_tiled_32_rd,

 * just reading 32 bytes per row instead of the 16 - that eases timing

 * Start burst should be even (LSB is ignored)

 * Description: Command sequencer generator for writing a tiled area

 * up to 1 kB. Memory is mapped so 8 consecuitive rows have same RA, CA

 * and alternating BA (0 to 7). Data will be read in columns 16 bytes wide,

 * then proceding to the next column (if >1).

 * This is a modification of module: cmd_encod_tiled_32_wr,

 * just writing 32 bytes per row instead of the 16 - that eases timing

 * Start burst should be even (LSB is ignored)

TODO  Comments from cmd_encod_tiled_rd, update

Minimal ACTIVATE period =4 Tcm or 10ns, so maximal no-miss rate is Tck=1.25 ns (800 MHz)

Minimal window of 4 ACTIVATE pulses - 16 Tck or 40 (40 ns), so one ACTIVATE per 8 Tck is still OK down to 1.25 ns

Reads are in 16-byte colums: 1 8-burst (16 bytes) in a row, then next row, bank inc first. Then (if needed) - next column

Number of rows should be >=5 (4 now for tCK=2.5ns to meet tRP (precharge to activate) of the same bank (tRP=13ns)

Can read less if just one column

TODO: Maybe allow less rows with different sequence (no autoprecharge/no activate?) Will not work if row crosses page boundary

number fo rows>1!

Known issues:

1: Most tile heights cause timing violation. Valid height mod 8 can be 0,6,7 (1,2,3,4,5 - invalid)

2: With option "keep_open" there should be no page boundary crossings, caller only checks the first line, and if window full width

 is not multiple of CAS page, page crossings can appear on other than first line (fix caller to use largest common divider of page and

 frame full width? Seems easy to fix
