20 Note: U-Boot supports two methods of booting a PowerPC Linux kernel: old way,
22 kernel is passed a pointer to the FDT. The boot method is indicated for each
26 1.  bootm		boot image at the current address, equivalent to 2,3,8
30 3.  bootm <addr1>		    /* multi-image at <addr1>  */
31 4.  bootm <addr1> -		    /* multi-image at <addr1>  */
34 7.  bootm <addr1> -	  <addr3>   /* single image at <addr1> */
39 10. bootm [<addr1>]#<conf>[#<extra-conf[#...]]
43 14. bootm [<addr1>]:<subimg1> -			  [<addr3>]:<subimg3>
44 15. bootm [<addr1>]:<subimg1> -			  <addr3>
49 - boot method: see cases 2,3,8
51 Ad. 2. Boot kernel image located at <addr1>.
52 - boot method: non-FDT
57 - boot method: depends on the number of components at <addr1>, and on whether
58   U-Boot is compiled with OF support:

63 #ifdef CONFIG_OF_*  |		    non-FDT |			FDT |
64 #ifndef CONFIG_OF_* |		    non-FDT |		    non-FDT |
67 component of the multi-image is irrelevant (it can be a dummy, 1-byte file).
68 - boot method: see case 3
70 Ad. 5. Boot kernel image located at <addr1> with initrd loaded with ramdisk
72 - boot method: non-FDT
77 - boot method: FDT
81 - boot method: FDT
85 - boot method: FDT or non-FDT, depending on whether the default configuration
88 Ad. 9. Similar to case 2: boot kernel stored in <subimg1> from the image at
90 - boot method: non-FDT
92 Ad. 10. Boot configuration <conf> from the image at <addr1>.
93 - boot method: FDT or non-FDT, depending on whether the configuration given
96 Ad. 11. Equivalent to case 5: boot kernel stored in <subimg1> from the image
99 - boot method: non-FDT
101 Ad. 12. Equivalent to case 6: boot kernel stored in <subimg1> from the image
104 - boot method: FDT
108 - boot method: FDT
110 Ad. 14. Equivalent to case 7: boot kernel stored in <subimg1> from the image
113 - boot method: FDT
117 - boot method: FDT

126 - new uImage sub-image specification
127 <addr>:<sub-image unit_name>
129 - new uImage configuration specification
132 - new uImage configuration specification with extra configuration components
141 - boot kernel "kernel@1" stored in a new uImage located at 200000:
144 - boot configuration "cfg@1" from a new uImage located at 200000:
147 - boot configuration "cfg@1" with extra "cfg@2" from a new uImage located
151 - boot "kernel@1" from a new uImage at 200000 with initrd "ramdisk@2" found in
155 - boot "kernel@2" from a new uImage at 200000, with initrd "ramdisk@1" and FDT
159 - boot kernel "kernel@2" with initrd "ramdisk@2", both stored in a new uImage
163 - boot kernel "kernel@2" from new uImage at 200000 with FDT "fdt@1" from the
165 bootm 200000:kernel@2 - 200000:fdt@1
