* Make sure that argv[] argument pointers are not modified.Wolfgang Denk2010-07-04-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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) { ...

* USB OHCI support for at91sam9g45 SoCSergey Matyukevich2010-06-30-2/+12
| | | | | | | | | | Add USB OHCI support for at91sam9g45ekes/at91sam9m10g45ek boards. Note that according to errata from Atmel, OHCI is not operational on the first revision of at91sam9g45 chip. So this patch enables OHCI support for later revisions. Signed-off-by: Sergey Matyukevich <geomatsi@gmail.com>

| * DaVinci: EMAC: Get EMAC_MDIO_PHY_NUM from config filesPrakash PM2010-06-22-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently EMAC_MDIO_PHY_NUM is defined as 1 in emac_defs.h. Because of this, EMAC does not work on EVMs which do not have phy connected at 1. Moving the macro to board config file makes this configurable depending on where the phy is connected on the MDIO bus. This patch fixes the board reset issue observed during network access on DM365EVM. EMAC driver was assuming EMAC_MDIO_PHY_NUM as 1 but it is 0 on DM365EVM. This patch is verified on da830/omap-l137, dm365 and dm644x evms. Signed-off-by: Prakash PM <prakash.pm@ti.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ARM ABI requires that the stack be aligned to 8 bytes as it is noted in Procedure Call Standard for the ARM Architecture: http://infocenter.arm.com/help/topic/com.arm.doc.ihi0042d/index.html Unaligned SP also causes the problem with variable-length arrays allocation when VLA address becomes less than stack pointer during aligning of this address, so the next 'push' in the stack overwrites first 4 bytes of VLA.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Part of this patch is by: Mikhail Kshevetskiy. Stack must be aligned to 8 bytes on PXA (possibly all armv5te) for LDRD/STRD instructions. In case LDRD/STRD is issued on an unaligned address, the behaviour is undefined. The issue was observed when working with the NAND code, which was rendered disfunctional. Also, the vsprintf() function had serious problems with printing 64bit wide long longs. After aligning the stack, this wrong behaviour is no longer present.

| * | ARM1136: Fix cache_flush() error and correct cpu_init_crit() commentsGeorge G. Davis2010-06-01-2/+3
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ARM1136 cache_flush() function uses the "mcr p15, 0, rn, c7, c7, 0" instruction which means "Invalidate Both Caches" when in fact the intent is to clean and invalidate all caches. So add an "mcr p15, 0, %0, c7, c10, 0" instruction to "Clean Entire Data Cache" prior to the "Invalidate Both Caches" instruction to insure that memory is consistent with any dirty cache lines. Also fix a couple of "flush v*" comments in ARM1136 cpu_init_crit() so that they correctly describe the actual ARM1136 CP15 C7 Cache Operations used. Signed-off-by: George G.
