Add support for the CENTIPAD board (http://www.harerod.de/centipad/index.html) (which is a very cool, very small ARM board) Add support for KB9202B (it has different memory) Make BOOT_FLAVOR settable Minor cleanup nits Approved by: re@

fast enough, or there's other issues that cause the first try to fail.

RTC_TIMR's RTC_SEC field is BCD. That makes it unsuitable for

2007-03-28T22:40:37Z

GetSeconds(). Instead, use CRTR register shifted right 15. This gives us a range of 32 seconds we can do for timeout. Shift to using == rather than < or > for calculating the timeout, since if we can't read the ST_CTRT register twice in a second we have even bigger problems to worry about, and == deals with the 'wrap' issue. This lets me type at the boot2 prompt again! Woo Hoo! Bogusness noticed by: tisco Pointy Hat to: That silly imp guy

Since we're about to set ST_RTMR to 1 to increase the accuracy of the

All SD cards have a block size of 512. The READ_BL_LEN field in the

2007-03-28T22:31:32Z

CSD is usually 512 (well, 9), but for 2GB (and the rogue 4GB SD cards) it is 1024 (or 2048 for 4GB). This value doesn't work for the block read commands (which really want 512). Hardcode 512 for those. This may break really old MMC cards that don't have a 512 block size (I've never seen one: make my day and send me one :-), but since the MMC side of the house is currently broken, it should only have the effect that 2GB (and non-conforming 4GB) SD cards will work. My 'non-conforming' 4GB SD card also works now too. The non-conforming 4GB SD cards were sold for a while before the SD association was worried they would be (a) incompatible (different FAT flavor on them) and (b) confusing for the new SDHC standard and cracked down on suppliers' bogus use of the SD trademark...

Various buglets fixed (from submitter):

2007-03-28T21:18:45Z

The changes to getstr() is so that the character that is passed in to it, is also processed just as the rest. I also removed one of the getc() calls otherwise you loose every second character. I also changed the strcpy of kname, so that it only happens if kname is '\0'. This is so that one can pass a kernel in through /boot.config. The last change to boot2.c is in parse(). If you tried to type a kernel name to boot, the first character was lost, the arg-- fix that. Submitted by: jhay
