* a4m072: change 'display' command implementationIlya Yanok2010-10-21-39/+23
| | | | | | | | | | | | | | | | | | | | | | This patch changes implementation of 'display' command for a4m072 that uses 7-segment LED display as customer requested: a) The "display" command shall _not_ turn on the decimal point. b) Exception: "display ." shall turn on (only) the decimal point. c) Hex digits (0-9, A-F, a-f) shall be displayed as usual. d) Letters U, P, Y, L, S, T, H shall be displayed as usual (lower case letters identical to upper case letters) e) 'I' (and 'i') shall be displayed like '1' f) 'O' (and 'o') shall be displayed like '0' g) all other Characters shall be displayed like ' ' (all segments off).

* a4m072: support for SHOW_BOOT_PROGRESS feature using LED displayIlya Yanok2010-10-12-5/+74
| | | | | | | | | | | | | | | | | | | | | | This patch adds support for displaying boot progress codes on a4m072 board using LED display. As we can display only one symbol at any time on the hardware (two symbols with blinking) we can't display progress codes directly and have to map them to 2-symbol codes. We use the following mapping on the a4m972 board: [1, 8] U [100, 108] -> 5 [-9, -1] U [-101, -100] U [-113, -103] -> -5 [9, 14] U [120, 123] U [125, 129] -> 8 [-13, -10] U [-122, -120] U [-127, -124] U {-129} -> -8 {15} -> 9 [-32, -30] -> -A [-40, -35] U [-51, -42] U [-58, -53] U [-83, -80] U {-64, -130, -140, -150} -> -B Other progress code are ignored. One symbol codes are displayed steady while two-symbol codes are displayed using blinking. Boot progress codes are displayed with decimal got unset (as opposed to 'display' command output).
