* edb93xx: Fix SDRAM initializationMatthias Kaehlcke2010-03-07-8/+31
| | | | | | | | | edb93xx: Fix SDRAM initialization by issuing a precharge all command before forcing the precharge and select mode register update mode before programming the mode registers. Write to the SDRAM banks in order to force a precharge, reading causes the edb93xx boards to hang Signed-off-by: Matthias Kaehlcke <matthias@kaehlcke.net>
* edb93xx: enable the uart in devicecfg registerAlessandro Rubini2010-02-12-0/+6
| | | | | | | printf goes to uart1, but it will block forever waiting for busy to go off unless the uart is enabled first. Signed-off-by: Alessandro Rubini <rubini@gnudd.com>
* edb93xx: change calculation un early_udelay.hAlessandro Rubini2010-02-12-1/+1
| | | | | | | | | | | | Previous code compiled with gcc-4.2.2 makes a call to __aeabi_uidiv to divide by 20. As a side effect it was not inline any more, and so sdram_cfg used the stack as well, but this is early code that has no stack yet. The patch explicitly removes the division, so no stack is used. The calculation of the counter calls a division by 20 Signed-off-by: Alessandro Rubini <rubini@gnudd.com>
