-----Original Message----- From: Simon Guinot [mailto:sguinot@lacie.com] Sent: Monday, May 02, 2011 2:40 AM To: Prafulla Wadaskar; Albert ARIBAUD; Wolfgang Denk Cc: u-boot@lists.denx.de; Simon Guinot Subject: [PATCH v2 3/6] Kirkwood: allow to override CONFIG_SYS_TCLK
This patch allow to override CONFIG_SYS_TCLK from board configuration files. This is needed for the Network Space v2 which use a non standard core clock frequency (166MHz instead of 200MHz for a 6281 SoC).
As a possible enhancement for 6281 and 6282 devices, TCLK could be dynamically detected by checking the Sample at Reset register bit 21.
Additionally this patch fix a typo.
