2010-09-08ARMV7: OMAP3: Remove erroneous hard coded sdram setup for 128MB/bankSteve Sakoman
Upcoming Beagle and Overo revisions use POP memory with 256MB or 512MB per bank. This patches uses the SDRC settings from x-load or the config header to set up timing properly. Signed-off-by: Steve Sakoman <steve@sakoman.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
2010-09-08ARMV7: OMAP3: Fix broken reset command on OMAP36XX/37XX and OMAP4Steve Sakoman
Using the reset command on OMAP36XX/37XX and OMAP4 caused a hang. This patch uses the reset bit appropriate for each CPU architecture. Signed-off-by: Steve Sakoman <steve@sakoman.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
2010-09-08ARMV7: OMAP3: Apply Cortex-A8 errata workarounds only on affected revisionsMans Rullgard
The workarounds for errata 621766 and 725233 should only be applied on affected Cortex-A8 revisions. Recent chips use r3px cores where these have been fixed.

2010-09-08ARMV7: OMAP3: Convert setup_auxcr() to pure asmMans Rullgard
This function consists entirely of inline asm statements, so writing it directly in a .S file is simpler. Additionally, the inline asm is not safe as is, since registers are not guaranteed to be preserved between asm() statements.

2010-09-08ARMV7: OMAP3: Fix and clean up L2 cache enable/disable functionsMans Rullgard
On OMAP34xx ES1.0, the L2 enable bit can only be set in secure mode, so an SMC call to the ROM monitor is required. On later versions, and on newer devices, this bit is banked and we can set it directly. The code checked only the ES revision of the chip, and hence incorrectly used the ROM call on ES1.0 versions of other devices. This patch adds a check for chip family as well as revision, and also removes some code duplication between the enable and disable functions.

Turn all ORION5X_DEF{ADR,SZ}_xxx macros into ORION5X_{ADR,SZ}_xxx and allow defining them from board code to override defaults.

2010-08-04Rename getenv_r() into getenv_f()Wolfgang Denk
While running from flash, i. e. before relocation, we have only a limited C runtime environment without writable data segment. In this phase, some configurations (for example with environment in EEPROM) must not use the normal getenv(), but a special function. This function had been called getenv_r(), with the idea that the "_r" suffix would mean the same as in the _r_eentrant versions of some of the C library functions (for example getdate vs. getdate_r, getgrent vs. getgrent_r, etc.). Unfortunately this was a misleading name, as in U-Boot the "_r" generally means "running from RAM", i. e. _after_ relocation. To avoid confusion, rename into getenv_f() [as "running from flash"] Signed-off-by: Wolfgang Denk <wd@denx.de> Acked-by: Detlev Zundel <dzu@denx.de>

2010-07-04Make sure that argv[] argument pointers are not modified.Wolfgang Denk
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) { ...
