[U-Boot-Users] ppc4xx/serial.c

hello, I've been going through the code of the function serial_init because I couldn't get the proper baudrate divisor. I must admit I don't understand the operations made to calculate udiv and bdiv... According to the 405gp user manual, these are the meanings of a few parameters. CFG_BASE_BAUD = SerClk / 16 bdiv = SerClk / (16 * baudrate) SerClk = cpu_freq / udiv As a result, udiv and bdiv should be generated as follows in serail_init: if external_clock: SerClk = CFG_EXT_SERIAL_CLK udiv = 1 else: SerClk = CFG_BASE_BAUD * 16 udiv = cpu_freq / serClk endif bdiv = SerClk / (16 * baudrate) Am I missing something? regards, François-Xavier SEINGIER

[U-Boot-Users] [PATCH] docecc.c include line
by Eisenhut, Daniel (MED) 11 Jul '04

11 Jul '04

The file common/docecc.c includes linux/mtd/doc2000.h prior to checking if CFG_CMD_DOC is used. This defines SECTORSIZE, ADDR_COLUMN, etc that is also being defined by various include/configs/* files for use with NAND. This causes an annoying compiler warning due to redefinition. Attached patch moves the #include line until after the check for CFG_CMD_DOC to prevent warning message. * Patch by Dan Eisenhut, 01 Jul 2004: Moved docecc.c include line to prevent compiler warning on some boards. Probably a bigger issue here with conflicting macro variables, just no one has used CMD_DOC and CMD_NAND at the same time yet.

It won't work with 2.95, but agree with Robert that we need to change at some point. Regards, Philippe

Hi, I ran in this typo while trying to use LCD on my arm platform. In lib_arm/board.c we should reserve LCD buffer memory at the end of bss, not at the start.
