dm: core: Create a new header file for 'compat' features

2020-02-06T02:33:46+00:00

At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.

Move the compatibility features into a separate header file.

common: Move hang() to the same header as panic()

2020-01-17T22:53:40+00:00

At present panic() is in the vsprintf.h header file. That does not seem
like an obvious choice for hang(), even though it relates to panic(). So
let's put hang() in its own header.

common: Move RAM-sizing functions to init.h

These functions relate to memory init so move them into the init
header.

fdtdec: only create phandle if caller wants it in fdtdec_add_reserved_memory()

2019-11-14T13:09:34+00:00

The phandlep pointer returning the phandle to the caller is optional
and if it is not set when calling fdtdec_add_reserved_memory() it is
highly likely that the caller is not interested in a phandle to the
created reserved-memory area and really just wants that area added.

So just don't create a phandle in that case.

fdtdec: protect against another NULL phandlep in fdtdec_add_reserved_memory()

2019-11-14T13:09:34+00:00

The change adding fdtdec_add_reserved_memory() already protected the added
phandle against the phandlep being NULL - making the phandlep var optional.

But in the early code checking for an already existing carveout this check
was not done and thus the phandle assignment could run into trouble,
so add a check there as well, which makes the function still return
successfully if a matching region is found, even though no-one wants to
work with the phandle.

fdt: Fix alignment issue when reading 64-bits properties from fdt

2019-10-27T19:01:53+00:00

The FDT specification [0] gives a requirement of aligning properties on
32-bits. Make sure that the compiler is aware of this constraint when
accessing 64-bits properties.

fdtdec: make CONFIG_OF_PRIOR_STAGE available in SPL

2019-08-26T08:07:42+00:00

The current preprocessor logic prevents CONFIG_OF_PRIOR_STAGE from being
used in U-Boot SPL. Change the logic to also make it available in U-Boot
SPL.
