函数原型：static struct resource *find_oprom(struct pci_dev *pdev)

返回类型：struct resource

参数：

类型参数名称
struct pci_dev *pdev
116  struct resource * oprom = NULL
119  以i小于ARRAY_SIZE - get the number of elements in array @arr*@arr: array to be sized(adapter_rom_resources)循环
120  res等于adapter_rom_resources[i]
124  如果end恒等于0则退出
127  rom等于isa_bus_to_virt(start)
128  如果probe_kernel_address(): safely attempt to read from a location*@addr: address to read from*@retval: read into this variable* Returns 0 on success, or -EFAULT.(rom + 0x18, offset)不等于0则继续下一循环
131  如果probe_kernel_address(): safely attempt to read from a location*@addr: address to read from*@retval: read into this variable* Returns 0 on success, or -EFAULT.(rom + offset + 0x4, vendor)不等于0则继续下一循环
134  如果probe_kernel_address(): safely attempt to read from a location*@addr: address to read from*@retval: read into this variable* Returns 0 on success, or -EFAULT.(rom + offset + 0x6, device)不等于0则继续下一循环
137  如果does this oprom support the given pci device, or any of the devices* that the driver supports?则
138  oprom等于res
139  退出
142  如果probe_kernel_address(): safely attempt to read from a location*@addr: address to read from*@retval: read into this variable* Returns 0 on success, or -EFAULT.(rom + offset + 0x8, list)恒等于0且probe_kernel_address(): safely attempt to read from a location*@addr: address to read from*@retval: read into this variable* Returns 0 on success, or -EFAULT.(rom + offset + 0xc, rev)恒等于0且rev大于等于3且list且probe_list(pdev, vendor, rom + offset + list)则
146  oprom等于res
147  退出
151  返回:oprom
