IDE: fix bug in reset sequence According to the ata (ata5) specification the RESET- signal shall be asserted for at least 25 us. Without this patch, the RESET- signal is asserted on some boards for only < 1 us (e. g. on the TQM5200). This patch adds a general delay of 25 us to the RESET- signal. Without this patch a Platinum 4 GiB CF card is not recognised properly on boards with a TQM5200 (STK52xx, TB5200). Signed-off-by: Martin Krause <martin.krause@tqs.de>
