1b6228f28d cpu: riscv: set correct SMBIOS processor family value
The SMBIOS specification requires to set the processor family in the type 4
(Processor Information) table to specific values depending only on the
bitness of the system (0x200 for RV32 and 0x201 for RV64).

With this patch dmidecode shows

    Handle 0x0004, DMI type 4, 48 bytes
    Processor Information
	Socket Designation: Not Specified
	Type: Central Processor
	Family: RV64

for qemu-riscv64_smode_defconfig.

f72d0d4a2f event: Convert existing spy records to simple
Very few of the existing event-spy records use the arguments they are

55171aedda dm: Emit the arch_cpu_init_dm() even only before relocation
The original function was only called once, before relocation. The new

448e2b6327 event: Correct dependencies on the EVENT framework
The event framework is just that, a framework. Enabling it by itself
does nothing, so we shouldn't ask the user about it. Reword (and correct
typos) around this the option and help text. This also applies to
DM_EVENT and EVENT_DYNAMIC. Only EVENT_DEBUG and CMD_EVENT should be
visible to the user to select, when EVENT is selected.

With this, it's time to address the larger problems. When functionality
uses events, typically via EVENT_SPY, the appropriate framework then
must be select'd and NOT imply'd. As the functionality will cease to
work (and so, platforms will fail to boot) this is non-optional and
where select is appropriate. Audit the current users of EVENT_SPY to
have a more fine-grained approach to select'ing the framework where
used. Also ensure the current users of event_register and also select
EVENT_DYNAMIC.

for PIT64B hardware timer, support for new at91 family SoC named sama7g5
which adds: clock support, including conversion of the clock tree to
CCF; SoC support in mach-at91, pinctrl and mmc drivers update.  The
feature set also includes updates for mmc driver and some other minor
fixes and features regarding building without the old Atmel PIT and the
possibility to read a secondary MAC address from a second i2c EEPROM.

sandbox,timebase-frequency-fallback controls whether sandbox_timer_probe
falls back to time_timebase_fallback or to SANDBOX_TIMER_RATE.

969251a5a4 uclass: cpu: fix to display proper CPU features
The cmd "cpu detail" fetches uninitialized cpu feature information
and thus displays wrong / inconsitent details as below.
For eg: FU540-C000 doesn't have any microcode, yet the cmd display's it.

=> cpu detail
  1: cpu@1      rv64imafdc
        ID = 1, freq = 999.100 MHz: L1 cache, MMU, Microcode, Device ID
        Microcode version 0x0
        Device ID 0x0
  2: cpu@2      rv64imafdc
        ID = 2, freq = 999.100 MHz: L1 cache, MMU, Microcode, Device ID
        Microcode version 0x0
        Device ID 0x0
  3: cpu@3      rv64imafdc
        ID = 3, freq = 999.100 MHz: L1 cache, MMU, Microcode, Device ID
        Microcode version 0x0
        Device ID 0x0
  4: cpu@4      rv64imafdc
        ID = 4, freq = 999.100 MHz: L1 cache, MMU, Microcode, Device ID
        Microcode version 0x0
        Device ID 0x0

The L1 cache or MMU entry seen above is also displayed inconsistently.
So initialize cpu information to zero into cpu-uclass itself so that
similar issues can be avoided for other CPU drivers.

We now see correct features as:
=> cpu detail
  1: cpu@1      rv64imafdc
        ID = 1, freq = 999.100 MHz
  2: cpu@2      rv64imafdc
        ID = 2, freq = 999.100 MHz
  3: cpu@3      rv64imafdc
        ID = 3, freq = 999.100 MHz
