It turns that this really doesn't work very nicely. Instead we should have a pre-console panic function so that we know that further execution is impossible and we don't need to worry about trampling on UARTs, etc. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Wolfgang Denk <wd@denx.de>

Add board_pre_console_putc to deal with early console output 2011-12-09T13:44:22+00:00 Simon Glass sjg@chromium.org 2011-10-18T13:43:20+00:00 295d3942b806552503243f5cfb36aec6f1b5a9bf This patch adds support for console output before the console is inited. The main purpose of this is to deal with a very early panic() which would otherwise cause a silent hang. A new board_pre_console_putc() function is added to the board API. If provided by the board it will be called in the event of console output before the console is ready. This function should turn on all UARTs and spray the character out if it possibly can. The feature is controlled by a new CONFIG_PRE_CONSOLE_PUTC option. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Graeme Russ <graeme.russ@gmail.com>

console: Implement pre-console buffer 2011-10-05T20:03:09+00:00 Graeme Russ graeme.russ@gmail.com 2011-09-01T00:48:27+00:00 9558b48af006a34d3ab7f0bd13a76b97acd45e47 Allow redirection of console output prior to console initialisation to a temporary buffer. To enable this functionality, the board (or arch) must define: - CONFIG_PRE_CONSOLE_BUFFER - Enable pre-console buffer - CONFIG_PRE_CON_BUF_ADDR - Base address of pre-console buffer - CONFIG_PRE_CON_BUF_SZ - Size of pre-console buffer (in bytes) The pre-console buffer will buffer the last CONFIG_PRE_CON_BUF_SZ bytes Any earlier characters are silently dropped.

console.c: fix problem with splashimage 2010-03-21T21:22:53+00:00 Anatolij Gustschin agust@denx.de 2010-03-16T14:29:33+00:00 a74908161a1b37d780d3a826a86807bbc50a3857 If a board uses cfb_console driver and splash image and also defines CONFIG_SILENT_CONSOLE, the user is locked out even if "silent" is not set. It is not possible to get any output, neither on vga console device nor on serial console after redirecting the output to the serial console, since the GD_FLG_SILENT flag remains set. Fix the problem by redirecting the output from frame buffer to serial console if splashimage is used. Only suppress the output if "silent" environment variable was set and don't set the GD_FLG_SILENT flag arbitrarily. Signed-off-by: Anatolij Gustschin <agust@denx.de>
