I've run some tests with the following 2 Kirkwood boards: Cloud
Engines Pogo V4 88F6192 (with CONFIG_DM_RTC and CONFIG_RTC_EMULATION),
and Marvell Sheevaplug 88F6281 (with CONFIG_DM_RTC and CONFIG_RTC_MV).

It seems that it was either frozen or the timer did not expire at some
subsequent sleep commands. Sometime it happened at 2nd command, some
time at a later sleep command. For example,

=== Pogo V4 (the 1st sleep command works correctly at 10 seconds on my
stopwatch)

U-Boot 2022.10-rc3-00048-g66ccd87a9c-dirty (Aug 30 2022 - 13:38:24 -0700)
Pogoplug V4

Hit any key to stop autoboot:  0
Pogo_V4> sleep 10
Pogo_V4> sleep 31.5
<frozen here>

=== Sheevaplug (RTC battery is old, so the date was not updated, but
the clock seems OK)

U-Boot 2022.10-rc3-00048-g66ccd87a9c-dirty (Aug 30 2022 - 14:14:24 -0700)
Marvell-Sheevaplug
Hit any key to stop autoboot:  0
=> date
Date: 2000-01-01 (Saturday)    Time:  0:02:55
=> sleep 10
=> date
Date: 2000-01-01 (Saturday)    Time:  0:03:18
=> sleep 10
=> sleep 20.1
<frozen here>

Please let me know what I can do (i.e. perhaps running a debug patch).
Thanks,
Tony
