test: call hexdump tests via `ut lib`

2019-04-22T22:13:21+00:00

The unit tests in test/lib/hexdump.c are not related to the device tree.
So they should be executed via `ut lib` and not via `ut dm`.

test: provide unit test for memory functions

2019-02-09T12:50:53+00:00

Memory functions may have architecture specific implementations. These
should be tested.

Provide unit tests for memset(), memcpy(), memmove().

Provide a 'ut lib' sub-command to execute the tests.

DRAM banks works correctly.

lib: lmb: rename lmb_get_unreserved_size to lmb_get_free_size

2019-01-26T13:13:57+00:00

As a follow-up, change the name of the newly introduced function
'lmb_get_unreserved_size' to 'lmb_get_free_size', which is more
appropriate.

lib: lmb: extend lmb for checks at load time

2019-01-16T21:37:04+00:00

This adds two new functions, lmb_alloc_addr and
lmb_get_unreserved_size.

lmb_alloc_addr behaves like lmb_alloc, but it tries to allocate a
pre-specified address range. Unlike lmb_reserve, this address range
must be inside one of the memory ranges that has been set up with
lmb_add.

lmb_get_unreserved_size returns the number of bytes that can be
used up to the next reserved region or the end of valid ram. This
can be 0 if the address passed is reserved.

Added test for these new functions.

lib: lmb: reserving overlapping regions should fail

2019-01-16T21:37:00+00:00

lmb_add_region handles overlapping regions wrong: instead of merging
or rejecting to add a new reserved region that overlaps an existing
one, it just adds the new region.

Since internally the same function is used for lmb_alloc, change
lmb_add_region to reject overlapping regions.

Also, to keep reserved memory correct after 'free', reserved entries
created by allocating memory must not set their size to a multiple
of alignment but to the original size. This ensures the reserved
region is completely removed when the caller calls 'lmb_free', as
this one takes the same size as passed to 'lmb_alloc' etc.

Add test to assert this.

lmb: fix allocation at end of address range

2019-01-16T21:36:48+00:00

The lmb code fails if base + size of RAM overflows to zero.

Fix this by calculating end as 'base + size - 1' instead of 'base + size'
where appropriate.

Added tests to assert this is fixed.
