Correct vxWorks elf boot to load at correct address

2013-12-13T14:17:32+00:00

argv[0] contains bootvx (command name) not the load address, if called with
argv < 2 use load_addr, else use address argument given to the command.

bootm: Correct the arguments for the ELF image loader

2013-07-12T14:32:39+00:00

The arguments were out of place since commit 983c72f, since this file was
missed and not tested. Correct this.

common: cmd_elf.c: use uintptr_t for casts from u32 to void*

This fixes warnings when compiling with ELDK-5.2.1 for MIPS64:

cmd_elf.c: In function 'load_elf_image_phdr':
cmd_elf.c:289:15: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]

bootvx: Clear and disable data cache, and call vxWorks with parameter.

2012-03-18T19:14:05+00:00

This patch clear and disable the data cache for vxWorks.

The entry point sysInit(int) intended by Windriver to be called from
the vxWorks bootrom, a very small vxWorks system.
The routine is called by the go() handler in the bootrom, that clears
the cache from start of image to end of usable memory.

The PowerPC implementations only invalidates and disable the cache,
the ARM implementations also flush it.

U-Boot will be on the safe side, if it disables the data cache before
calling vxWorks sysInit(int).

net: tftpput: Rename TFTP to TFTPGET

2011-10-26T19:33:42+00:00

This is a better name for this protocol. Also remove the typedef to keep
checkpatch happy, and move zeroing of NetBootFileXferSize a little
earlier since TFTPPUT will need to change this.

cmd_elf: add an option for loading ELFs according to PHDRs

2010-10-06T20:42:14+00:00

The current ELF loading function does a lot of work above and beyond a
simple "loading".  It ignores the real load addresses and loads things
into their virtual (runtime) address.  This is undesirable when we just
want it to load an ELF and let the ELF do the actual C runtime init.

So add a command line option to let people choose to load via either the
program or section headers.  I'd prefer to have program header loading
be the default, but this would break historical behavior, so I'll leave
section header loading as the norm.

Make sure that argv[] argument pointers are not modified.

2010-07-04T21:55:42+00:00

The hush shell dynamically allocates (and re-allocates) memory for the
argument strings in the "char *argv[]" argument vector passed to
commands.  Any code that modifies these pointers will cause serious
corruption of the malloc data structures and crash U-Boot, so make
sure the compiler can check that no such modifications are being done
by changing the code into "char * const argv[]".

This modification is the result of debugging a strange crash caused
after adding a new command, which used the following argument
processing code which has been working perfectly fine in all Unix
systems since version 6 - but not so in U-Boot:

int main (int argc, char **argv)
{
	while (--argc > 0 && **++argv == '-') {
/* ====> */	while (*++*argv) {
			switch (**argv) {
			case 'd':
				debug++;
				break;
			...
			default:
				usage ();
			}
		}
	}
	...
}

The line marked "====>" will corrupt the malloc data structures and
usually cause U-Boot to crash when the next command gets executed by
the shell.  With the modification, the compiler will prevent this with
an
	error: increment of read-only location '*argv'

N.B.: The code above can be trivially rewritten like this:

	while (--argc > 0 && **++argv == '-') {
		char *arg = *argv;
		while (*++arg) {
			switch (*arg) {
			...

Less verbose output when loading vxworks 6.x images

2009-07-26T22:15:53+00:00

Loading vxWorks 5.x images resulted just into 3 or 4 lines of output.
With vxWorks 6.x and the new GCC it emits about 30 lines, which is
far too noisy in my opinion.
