Re: [U-Boot-Users] [PATCH 3/3][MIPS] lib_mips/time.c: Fix improper use of CFG_HZ and timer routines

In message 483811E4.3070209@ruby.dti.ne.jp you wrote:

This patch adds 3 global variables; timestamp, cycles_per_jiffy, expirelo. timestamp is a 32-bit non-overflowing CFG_HZ counter. cycles_per_jiffy is calculated counter cycles in a CFG_HZ. And expirelo holds the count value for next CPU timer expiration.

Be careful - keep in mind that variables in the data segment will be read-only before relocation to RAM, and variables in BSS will be uninitialized *and* get overwritten with zero when the BSS gets initialized.
