Write to the SDRAM in order to force a precharge, reading causes the edb93xx boards to hang Signed-off-by: Matthias Kaehlcke <matthias@kaehlcke.net> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Matthias Kaehlcke authored on 24 Feb 2010 Sascha Hauer committed on 26 Feb 2010
2010-02-12	fbff755 Browse files » edb9302(a): Tweak PLL settings ... Previous code ran the edb9302(a) boards with the PLL same settings as the edb9301, at 166MHz core and 66MHz system bus clock. In difference to the edb9301 board the edb9302(a) is equipped with an EP9302 processor, which can be clocked at higher rates than the EP9301. Therefore we can configure the edb9302(a) with the same PLL settings as the other non-edb9301 boards, namely at 200MHz for the core and 100MHz for the system bus clock.

2010-02-08	63c194a Browse files » edb93xx: Avoid stack usage in early_udelay() ... edb93xx: The purpose of early_udelay() is to provide delay functionality in the early board setup, when the stack isn't set up yet. With some compiler versions the current implementation makes use of the stack and ends up crashing. Fix this by removing an explicit division from early_udelay() Signed-off-by: Matthias Kaehlcke <matthias@kaehlcke.net> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Matthias Kaehlcke authored on 6 Feb 2010 Sascha Hauer committed on 8 Feb 2010
