The pSeries machine never bothered with the common machine->fdt
attribute. We do all the FDT related work using spapr->fdt_blob.
We're going to introduce HMP commands to read and save the FDT, which
will rely on setting machine->fdt properly to work across all machine
archs/types.
Let's set
'info fdt' is only able to print full nodes so far. It would be good to
be able to also print single properties, since ometimes we just want
to verify a single value from the FDT.
libfdt does not have support to find a property given its full path, but
it does have a way to return a fdt_property
Printing subnodes of a given node will allow us to show a whole subtree,
which the additional perk of 'info fdt /' being able to print the whole
FDT.
Since we're now printing more than one subnode, change 'fdt_info' to
print the full path of the first node. This small tweak helps
identifying
To support printing string properties in 'info fdt' we need to determine
whether a void data might contain a string.
We do that by casting the void data to a string array and:
- check if the array finishes with a null character
- check if all characters are printable
If both conditions are met,
We want to be able to also print properties with 'info fdt'.
Create a helper to format properties based on the already existing code
from fdt_format_node().

Right now translator stops right *after* the end of a page, which
breaks reporting of fault locations when the last instruction of a
multi-insn translation block crosses a page boundary.
We may find out that we crossed page boundary after some ops were
emitted and cc_op was updated. In theory it

Coverity reports a OVERFLOW_BEFORE_WIDEN issue in dcr_write_dma(). When
handling the DMA0_CR switch we're doing a multiplication between two
integers (count and width), and the product is assigned to an uint64_t
(xferlen). The int32 product can be overflow before widened.
Fix it by casting the

The macros SET_FPU_* are used to set corresponding bits of fcsr.
Unfortunately it forgets to set the result and it causes fcsr's
"CAUSE" never being updated. This patch is to fix this bug.

Zoned Block Devices (ZBDs) devide the LBA space to block regions called zones
that are larger than the LBA size. It can only allow sequential writes, which
reduces write amplification in SSD, leading to higher throughput and increased
capacity. More details about ZBDs can be found at:
