* [U-Boot] [PATCH 0/4] Support for A4M072 board @ 2010-09-09 21:03 Ilya Yanok 2010-09-09 21:03 ` [U-Boot] [PATCH 1/4] A4M072: Added support for the board Ilya Yanok 0 siblings, 1 reply; 11+ messages in thread From: Ilya Yanok @ 2010-09-09 21:03 UTC (permalink / raw) To: u-boot These patches add support for A4M072 MPC5200-based board. The first patch adds new board with support for all devices except for 7-segment LED display. We've decided to use 'display' command to manipulate the LED display so the second patch adds very simple generic interface to use such devices and moves hw-specific realization to drivers/misc/pdsp188x.c The third patch adds 7-segment LED display support. And the fourth file adds support for showing boot progress codes on LED display (we can't display them directly so we use a mapping).

* [U-Boot] [PATCH 4/4] a4m072: support for SHOW_BOOT_PROGRESS feature using LED display 2010-09-09 21:03 ` [U-Boot] [PATCH 3/4] a4m072: led display support Ilya Yanok @ 2010-09-09 21:03 ` Ilya Yanok 2010-10-12 20:45 ` Wolfgang Denk 2010-10-12 20:45 ` [U-Boot] [PATCH 3/4] a4m072: led display support Wolfgang Denk 1 sibling, 1 reply; 11+ messages in thread From: Ilya Yanok @ 2010-09-09 21:03 UTC (permalink / raw) To: u-boot 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).
