# Set up PXE boot for Ironic
#
# === Parameters
#
# [*package_ensure*]
# (optional) Control the ensure parameter for the package resource
# Defaults to 'present'
#
# [*tftp_root*]
# (optional) Folder location to deploy PXE boot files
# Defaults to '/tftpboot'
#
# [*http_root*]
# (optional) Folder location to deploy HTTP PXE boot
# Defaults to '/httpboot'
#
# [*http_port*]
# (optional) port used by the HTTP service serving introspection and
# deployment images.
# Defaults to '8088'
#
# [*syslinux_path*]
# (optional) Path to directory containing syslinux files.
# Setting this to False will skip syslinux related resources.
# Defaults to '$::ironic::params::syslinux_path'
#
# [*syslinux_files*]
# (optional) Array of PXE boot files to copy from $syslinux_path to $tftp_root.
# Defaults to '$::ironic::params::syslinux_files'
#
# [*tftp_bind_host*]
# (optional) The IP address xinetd will listen on for TFTP.
# Defaults to undef (listen on all ip addresses).
#
# [*enable_ppc64le*]
# (optional) Boolean value to dtermine if ppc64le support should be enabled
# Defaults to false (no ppc64le support)
#
# [*ipxe_name_base*]
# (optional) Beginning of the source file name which is copied to
# $tftproot/ipxe.efi. Setting this to 'ipxe-snponly' on CentOS8 would result
# in the source file being /usr/share/ipxe/ipxe-snponly-x86_64.efi
# Defaults to 'ipxe-snponly'
#
# [*uefi_ipxe_bootfile_name*]
# (optional) Name of efi file used to boot servers with iPXE + UEFI. This
# should be consistent with the uefi_ipxe_bootfile_name parameter in pxe
# driver.
# Defaults to 'snponly.efi'
#
