Orange PI Zero's processor Allwinner H2+ doesn't support SMMU. In the attached
non-root-linux demo config file, what's the following section for?
/* RAM */ {
.phys_start = 0x57000000,
.virt_start = 0x57000000,
.size = 0x7ef0000,
.flags = JAILHOUSE_MEM_READ | JAILHOUSE_MEM_WRITE |
JAILHOUSE_MEM_EXECUTE | JAILHOUSE_MEM_DMA |
JAILHOUSE_MEM_LOADABLE,
},
Thanks!
