85xx: Round up frequency calculations to get reasonable output

2008-04-24T13:42:35+00:00

eg. because of rounding error we can get 799Mhz instead of 800Mhz.

Introduced DIV_ROUND_UP and roundup taken from linux kernel.

85xx: Show DDR memory data rate in addition to the memory clock frequency.

2008-03-26T16:43:04+00:00

Show the DDR memory data rate in addition to the memory clock
frequency.  For DDR/DDR2 memories the memory data rate is 2x the
memory clock.

85xx: get_tbclk() speed up and rounding fix

2008-03-26T16:43:04+00:00

Speed up get_tbclk() by referencing pre-computed bus clock
frequency value from global data instead of sys_info_t.  Fix
rounding of result to nearest; previously it was rounding
upwards.

Update SVR numbers to expand support

2008-03-26T16:43:04+00:00

FSL has taken to using SVR[16:23] as an SOC sub-version field.  This
is used to distinguish certain variants within an SOC family.  To
account for this, we add the SVR_SOC_VER() macro, and update the SVR_*
constants to reflect the larger value.  We also add SVR numbers for all
of the current variants.  Finally, to make things neater, rather than
use an enormous switch statement to print out the CPU type, we create
and array of SVR/name pairs (using a macro), and print out the CPU name
that matches the SVR SOC version.

Handle Asynchronous DDR clock on 85xx

2007-12-12T04:34:20+00:00

The MPC8572 introduces the concept of an asynchronous DDR clock with
regards to the platform clock.

Introduce get_ddr_freq() to report the DDR freq regardless of sync/async
mode.

Stop using immap_t on 85xx

2007-12-12T04:34:20+00:00

In the future the offsets to various blocks may not be in same location.
Move to using CFG_MPC85xx_*_ADDR as the base of the registers
instead of getting it via &immap.

Reduce CONFIG_MPC8YXX_TSECx to CONFIG_TSECx

2007-05-16T22:07:21+00:00

For all practical u-boot purposes, TSECs don't differ throughout the
mpc8[356]xx families; reduce CONFIG_MPC8YXX_TSECx to CONFIG_TSECx.
