On the 32bit ARM sandbox 'dm ut dm_test_devm_regmap' fails with an abort.
This is due to incorrect range checks.
On 32-bit systems the size of size_t and int is both 32 bit. The expression
(offset + val_len) is bound to overflow if offset == -1. Add an overflow
check.

Move the code making sure that the timer is initialized only once into
orion_timer_init(), which is called from timer_early_init() and from
orion_timer_probe(). This way the timer is not re-initialized.

Replace the if/else chain in pxa_ecc_init() with a lookup table. This
makes the code more concise and hopefully easier to follow. Remove the
unused ecc_layout tables and replace it with a single dummy one (the
pxa3xx driver has never used this but the mtd subsystem expects it to be
provided).

At present ofnode_write_prop() is inconsistent between livetree and
flattree, in that livetree requires the caller to ensure the property
value is stable (e.g. in rodata or allocated) but flattree does not, since
it makes a copy.
This makes the API call a bit painful to use, since the caller must do
different things depending on OF_LIVE.
Add a new 'copy' argument which tells the function to make a copy if
needed. Add some tests to cover this behaviour.

We need to be able to look up phandles in any FDT, not just the control
FDT. Use the 'other' FDT to test this, with a helper function which gets
this as an oftree that can then we used as needed.
Add a few more tests and some comments at the top of the file, to explain
what is going on.

Add the logic to redirect requests for the device tree through a function
which can look up the tree ID. This works by using the top bits of
ofnode.of_offset to encode a tree.
It is assumed that there will only be a few device trees used at runtime,
typically the control FDT (always tree ID 0) and possibly a separate FDT
to be passed the OS.
The maximum number of device trees supported at runtime is 8, with this
implementation. That would use bits 30:28 of the node-offset value,
meaning that the positive offset range is limited to bits 27:0, versus
30:1 with this feature disabled. That still allows a device tree of up
to 256MB, which should be enough for most FITs. Larger ones can be
supported by using external data with the FIT, or by enabling OF_LIVE.
Update the documentation a little and fix up the comment for
ofnode_valid().
Signed-off-by: Simon Glass <sjg@chromium.org>
At present, unless OF_LIVE is enabled, ofnode only supports access to one
device tree, the control FDT. This is because only the node offset is
encoded in ofnode, with the tree being implicit.
This makes ofnode (without OF_LIVE) unsuitable for device tree fixups, as
implemented by ft_board_setup() and other such functions.
To solve this, we can use the top bits of the node offset to hold a tree
ID.
Add the definitions for this.

This function turns out to be a little confusing since it looks up a path
and also registers the tree. Split it into two, one that gets the root
node and one that looks up a path, so the purpose is clear.
Registering the tree will happen in a function to be added in a later
patch, called oftree_from_fdt().

In some cases we want to obtain an ofnode in the same tree as a different
ofnode, such as when looking up a subnode. At present this is trivial,
since there is only one tree. When there are multiple trees, this
implementation will change.
Also move the ofnode_to_offset() function up higher in the header file,
since we will need to provide a different implementation with multiple
trees.
Signed-off-by: Simon Glass <sjg@chromium.org>
When we have multiple trees, the ofnode logic needs to be told which one
to use. Create a new function which takes an oftree argument, along with
a helper to obtain the FDT pointer from an oftree.

The current implementation creates a 'name' value for every node. This
is not needed for the latest device tree format, which includes a name in
the node header.
Adjust the code to point the name at the node header instead.
Also simplify ofnode_get_name(), now that we can rely on it to set the
name correctly. Update the comment to make it clear what name the root
node has.

The udelay() function in lib/time.c contains a WATCHDOG_RESET()
call. The only reason this doesn't lead to a catastrophic infinite
recursion is due to the rate-limiting in wdt-uclass.c:
if (time_after_eq(now, priv->next_reset)) {
priv->next_reset = now + priv->reset_period;
wdt_reset(dev);
}
But this would fall apart if ->next_reset was updated after calling the
device's reset method.
This is needlessly fragile, and it's easy enough to avoid that
recursion in the first place by just using __udelay() directly.
