Alistair FrancisandAnup Patel 215421ca61 lib: Remove date and time from init message
Building the date and time into the binary means the OpenSBI isn't
reproducible. We don't really need the time so let's remove it.

Alistair FrancisandAnup Patel 508a27204c lib: Create a sbi_ipi_data structure
Create a sbi_ipi_data structure that holds unpacked IPI information. At
the same time remove ipi_type from the sbi_scratch struct and use a
fixed offset to access it.

This structure fits in behind the sbi_scratch structure.

This fixes https://github.com/riscv/opensbi/issues/81

Alistair FrancisandAnup Patel 42e9ad556d Makefile: Set the platform variables before parsing the platforms
Ensure the platform variable PLATFORM_RISCV_XLEN is set before we parse
the platform files.

This fixes the 32-bit openSBI FW_JUMP_ADDR.

64. It also was not assigned before config.mk was parsed. Ensure that it
will always be assigned.

Alistair FrancisandAnup Patel d369e721e8 firmware: Ensure the payloads are 4 bit alligned
We expect the payloads to be 4 bit alligned as we later AND them
with ~0xf. As most of the addresses are manually specified we don't
really need this, but better to be over cautious.

csr_val is a tartget length based variable, so on 32-bit devices it's

In order to support 32-bit guests move the start address to a 4MB

let's just make this the default for both 32 and 64 bit kernels.
