| 1804config ARM_ATAG_DTB_COMPAT 1805 bool "Supplement the appended DTB with traditional ATAG information" 1806 depends on ARM_APPENDED_DTB 1807 help 1808 Some old bootloaders can't be updated to a DTB capable one, yet 1809 they provide ATAGs with memory configuration, the ramdisk address, 1810 the kernel cmdline string, etc. Such information is dynamically 1811 provided by the bootloader and can't always be stored in a static 1812 DTB. To allow a device tree enabled kernel to be used with such 1813 bootloaders, this option allows zImage to extract the information 1814 from the ATAG list and store it at run time into the appended DTB. 1815 |
