2020-08-23treewide: Use fallthrough pseudo-keywordGustavo A. R. Silva1-1/+1
Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

2020-01-21sparc32, leon: Stop adding vendor and device id to prom ambapp path componentsAndreas Larsson1-14/+4
These extra fields before the @ are not handled in of_node_name_eq, making commit b3e46d1a0590500335f0b95e669ad6d84b12b03a break node name comparisons for ambapp path components, thereby making LEON systems unable to boot. As there is no need for the tacked on vendor and device ID fields in the path component, resolve this situation by removing them.

2019-03-12sparc: add checks for the return value of memblock_alloc*()Mike Rapoport1-0/+2
Add panic() calls if memblock_alloc*() returns NULL. Most of the changes are simply addition of if(!ptr) panic(); statements after the calls to memblock_alloc*() variants. Exceptions are pcpu_populate_pte() and kernel_map_range() that were slightly refactored to accommodate the change.

2009-08-17sparc,leon: Added support for AMBAPP bus.Konrad Eisele1-0/+33
The device is a AMBA bus if it is a child of prom node "ambapp" (AMBA plug and play). Two functions leon_trans_init() and leon_node_init() (defined in sparc/kernel/leon_kernel.c) are called in the prom_build_tree() path if CONFIG_SPARC_LEON is defined. leon_node_init() will build up the device tree using AMBA plug and play. Also: a extra check was addes to prom_common.c:build_one_prop() in case a rom-node is undefined which can happen for SPARC-LEON because it creates only a minimum nodes to emulate sparc behaviour.
