Re: [Minios-devel] [UNIKRAFT PATCHv10 0/7] Add frequently usd APIs to fdt(series#2)

Hello Justin,

Thank you for all work in adding support for device tree to Unikraft. The patch series has been reviewed and I will upstream this patch series before tomorrow.

Thanks & Regards

Arm64 devices libraries will access device tree to get lots of
properties. We will get device addresses, interrupts in each device
library. In this case, we will find device node by offset, get address
cells, size cells and interrupt cells everywhere.

This patch series introduces several APIs in lib/fdt to reduce the
redundant calls of fdt functions.

   fix a warning in gcc 6.3 for patch 1
   remove redudant memset in "Add fdt address translation support"
   add r-b from Sharan
   merge build enablement patch into previous one
   move fdt_getprop_u32_by_offset into lib/fdt/uk_fdt.c
   move fdt_reg_read_number to header file for static inline
   fix one small compilation warning in patch 07
   1.address Sharan's comment
   2.remove fdt_{address,size}_cells_or_parent helpers as per comments
     from libfdt author
v3->v4: address the comments from Julien.
   1.add fdt translate address patch05 to handle the "ranges" property
   2.add fdt_{address,size}_cells_or_parent helpers patch04
   3.fix a default value bug which doesn't follow DT spec
v2->v3: address the comments from Julien.
   1.remove fdt_get_cells to keep libfdt unchanged
   2.parse "interrupt-extended" and "ranges"
   3.remove the size parameter in fdt_node_offset_by_compatible_list
   4.remove the fdt_for_each_compatible_node which is not used.
v1->v2: rebase to latest code.

   lib/fdt: Introduce fdt_getprop_u32_by_offset helper
   plat/common: Add fdt address translation support
   plat/common: Introduce fdt_get_address helper
   lib/fdt: Change the default value of fdt_size_cells

Jianyong Wu (2):
   plat/common: Introduce fdt_interrupt_cells helper to parse irq
   plat/common: Introduce fdt_node_offset_by_compatible_list helper

Wei Chen (1):
   plat/common: Introduce fdt_get_interrupt helper
