153 Xen is a virtual machine monitor (VMM) or a type-1 hypervisor with support
154 for para-virtualization. Xen can organize the safe execution of several
155 virtual machines on the same physical system with performance close to
156 native. It is used as the basis for a number of different commercial and
157 open source applications, such as: server virtualization, Infrastructure
158 as a Service (IaaS), desktop virtualization, security applications,
159 embedded and hardware appliances.
160 Xen has a special VM called Domain-0 that runs the Dom0 kernel and allows
161 Xen to use the device drivers for the Domain-0 kernel by default.

369 Some SoCs need special image types (e.g. U-Boot binary
370 with a special header) as build targets. By defining
371 CONFIG_BUILD_TARGET in the SoC / board header, this
372 special image will be automatically built upon calling
373 make / buildman.

376 bool "Use a custom location for the U-Boot linker script"
377 help
378 Normally when linking U-Boot we will look in the board directory,
379 the CPU directory and finally the "cpu" directory of the architecture
380 for the ile "u-boot.lds" and use that as our linker. However, in
381 some cases we need to provide a different linker script. To do so,
382 enable this option and then provide the location under
383 CONFIG_SYS_LDSCRIPT.

393 hex

395 help
396 Some U-Boot pointers have redundant information, so we can use a
397 scheme where we can return either an error code or a pointer with the
398 same return value. The default implementation just casts the pointer
399 to a number, however, this may fail on platforms where the end of the
400 address range is used for valid pointers (e.g. 0xffffff00 is a valid
401 heap pointer in socfpga SPL).
402 For such platforms, this value provides an upper range of those error
403 pointer values - up to 'MAX_ERRNO' bytes below this value must be
404 unused/invalid addresses.
