150 for para-virtualization. Xen can organize the safe execution of several
151 virtual machines on the same physical system with performance close to
152 native. It is used as the basis for a number of different commercial and
153 open source applications, such as: server virtualization, Infrastructure
154 as a Service (IaaS), desktop virtualization, security applications,
155 embedded and hardware appliances.
156 Xen has a special VM called Domain-0 that runs the Dom0 kernel and allows
157 Xen to use the device drivers for the Domain-0 kernel by default.

368 with a special header) as build targets. By defining
369 CONFIG_BUILD_TARGET in the SoC / board header, this
370 special image will be automatically built upon calling
371 make / buildman.

376 Normally when linking U-Boot we will look in the board directory,
377 the CPU directory and finally the "cpu" directory of the architecture
378 for the ile "u-boot.lds" and use that as our linker. However, in

380 enable this option and then provide the location under

407 help
408 Some U-Boot pointers have redundant information, so we can use a
409 scheme where we can return either an error code or a pointer with the
410 same return value. The default implementation just casts the pointer
411 to a number, however, this may fail on platforms where the end of the
412 address range is used for valid pointers (e.g. 0xffffff00 is a valid
413 heap pointer in socfpga SPL).
414 For such platforms, this value provides an upper range of those error
415 pointer values - up to 'MAX_ERRNO' bytes below this value must be
416 unused/invalid addresses.
